Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537978, here are decompositions:

  • 7 + 33537971 = 33537978
  • 17 + 33537961 = 33537978
  • 37 + 33537941 = 33537978
  • 59 + 33537919 = 33537978
  • 79 + 33537899 = 33537978
  • 139 + 33537839 = 33537978
  • 181 + 33537797 = 33537978
  • 211 + 33537767 = 33537978

Showing the first eight; more decompositions exist.
