Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731340, here are decompositions:

19 + 8731321 = 8731340
31 + 8731309 = 8731340
109 + 8731231 = 8731340
127 + 8731213 = 8731340
139 + 8731201 = 8731340
199 + 8731141 = 8731340
229 + 8731111 = 8731340
271 + 8731069 = 8731340

Showing the first eight; more decompositions exist.
