Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466786, here are decompositions:

  • 37 + 31466749 = 31466786
  • 67 + 31466719 = 31466786
  • 73 + 31466713 = 31466786
  • 79 + 31466707 = 31466786
  • 97 + 31466689 = 31466786
  • 157 + 31466629 = 31466786
  • 199 + 31466587 = 31466786
  • 223 + 31466563 = 31466786

Showing the first eight; more decompositions exist.
