Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526042, here are decompositions:

  • 61 + 31525981 = 31526042
  • 139 + 31525903 = 31526042
  • 151 + 31525891 = 31526042
  • 193 + 31525849 = 31526042
  • 271 + 31525771 = 31526042
  • 433 + 31525609 = 31526042
  • 439 + 31525603 = 31526042
  • 829 + 31525213 = 31526042

Showing the first eight; more decompositions exist.
