Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25040, here are decompositions:

  • 3 + 25037 = 25040
  • 7 + 25033 = 25040
  • 61 + 24979 = 25040
  • 73 + 24967 = 25040
  • 97 + 24943 = 25040
  • 151 + 24889 = 25040
  • 163 + 24877 = 25040
  • 181 + 24859 = 25040

Showing the first eight; more decompositions exist.
