Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731328, here are decompositions:

7 + 8731321 = 8731328
19 + 8731309 = 8731328
79 + 8731249 = 8731328
97 + 8731231 = 8731328
127 + 8731201 = 8731328
379 + 8730949 = 8731328
409 + 8730919 = 8731328
439 + 8730889 = 8731328

Showing the first eight; more decompositions exist.
