Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27974, here are decompositions:

  • 7 + 27967 = 27974
  • 13 + 27961 = 27974
  • 31 + 27943 = 27974
  • 73 + 27901 = 27974
  • 127 + 27847 = 27974
  • 151 + 27823 = 27974
  • 157 + 27817 = 27974
  • 181 + 27793 = 27974

Showing the first eight; more decompositions exist.
