Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5818, here are decompositions:
- 5 + 5813 = 5818
- 11 + 5807 = 5818
- 17 + 5801 = 5818
- 101 + 5717 = 5818
- 107 + 5711 = 5818
- 149 + 5669 = 5818
- 167 + 5651 = 5818
- 179 + 5639 = 5818
Showing the first eight; more decompositions exist.

A staple of calculator humor since pocket calculators put digits in front of bored students.
The digit sequence 5818 first appears in π at position 8,806 of the decimal expansion (the 8,806ordinal-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.
