Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37978, here are decompositions:

  • 11 + 37967 = 37978
  • 71 + 37907 = 37978
  • 89 + 37889 = 37978
  • 107 + 37871 = 37978
  • 131 + 37847 = 37978
  • 167 + 37811 = 37978
  • 179 + 37799 = 37978
  • 197 + 37781 = 37978

Showing the first eight; more decompositions exist.
