Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466530, here are decompositions:

  • 149 + 31466381 = 31466530
  • 239 + 31466291 = 31466530
  • 281 + 31466249 = 31466530
  • 467 + 31466063 = 31466530
  • 479 + 31466051 = 31466530
  • 701 + 31465829 = 31466530
  • 773 + 31465757 = 31466530
  • 857 + 31465673 = 31466530

Showing the first eight; more decompositions exist.
