Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42038, here are decompositions:

  • 19 + 42019 = 42038
  • 79 + 41959 = 42038
  • 97 + 41941 = 42038
  • 127 + 41911 = 42038
  • 151 + 41887 = 42038
  • 229 + 41809 = 42038
  • 277 + 41761 = 42038
  • 379 + 41659 = 42038

Showing the first eight; more decompositions exist.
