Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147503042, here are decompositions:

  • 5 + 2147503037 = 2147503042
  • 53 + 2147502989 = 2147503042
  • 71 + 2147502971 = 2147503042
  • 263 + 2147502779 = 2147503042
  • 383 + 2147502659 = 2147503042
  • 821 + 2147502221 = 2147503042
  • 1061 + 2147501981 = 2147503042
  • 1373 + 2147501669 = 2147503042

Showing the first eight; more decompositions exist.
