Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147552378, here are decompositions:

  • 7 + 2147552371 = 2147552378
  • 19 + 2147552359 = 2147552378
  • 241 + 2147552137 = 2147552378
  • 379 + 2147551999 = 2147552378
  • 577 + 2147551801 = 2147552378
  • 787 + 2147551591 = 2147552378
  • 991 + 2147551387 = 2147552378
  • 1117 + 2147551261 = 2147552378

Showing the first eight; more decompositions exist.
