Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5808, here are decompositions:

  • 7 + 5801 = 5808
  • 17 + 5791 = 5808
  • 29 + 5779 = 5808
  • 59 + 5749 = 5808
  • 67 + 5741 = 5808
  • 71 + 5737 = 5808
  • 97 + 5711 = 5808
  • 107 + 5701 = 5808

Showing the first eight; more decompositions exist.

Calculator-display word

Type 5,808 on a seven-segment calculator, flip it 180°, and the display reads:

BOBS

A staple of calculator humor since pocket calculators put digits in front of bored students.

Position in π

The digit sequence 5808 first appears in π at position 4,320 of the decimal expansion (the 4,320ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
