Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147424044, here are decompositions:

  • 37 + 2147424007 = 2147424044
  • 61 + 2147423983 = 2147424044
  • 127 + 2147423917 = 2147424044
  • 151 + 2147423893 = 2147424044
  • 163 + 2147423881 = 2147424044
  • 193 + 2147423851 = 2147424044
  • 223 + 2147423821 = 2147424044
  • 331 + 2147423713 = 2147424044

Showing the first eight; more decompositions exist.
