Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466942, here are decompositions:

  • 43 + 31466899 = 31466942
  • 151 + 31466791 = 31466942
  • 193 + 31466749 = 31466942
  • 211 + 31466731 = 31466942
  • 223 + 31466719 = 31466942
  • 229 + 31466713 = 31466942
  • 271 + 31466671 = 31466942
  • 313 + 31466629 = 31466942

Showing the first eight; more decompositions exist.
