Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731738, here are decompositions:

17 + 8731721 = 8731738
101 + 8731637 = 8731738
131 + 8731607 = 8731738
167 + 8731571 = 8731738
227 + 8731511 = 8731738
311 + 8731427 = 8731738
461 + 8731277 = 8731738
599 + 8731139 = 8731738

Showing the first eight; more decompositions exist.
