Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18848, here are decompositions:

  • 61 + 18787 = 18848
  • 157 + 18691 = 18848
  • 211 + 18637 = 18848
  • 307 + 18541 = 18848
  • 331 + 18517 = 18848
  • 367 + 18481 = 18848
  • 397 + 18451 = 18848
  • 409 + 18439 = 18848

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18848 first appears in π at position 543,825 of the decimal expansion (the 543,825ordinal-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.
