Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731430, here are decompositions:

3 + 8731427 = 8731430
13 + 8731417 = 8731430
61 + 8731369 = 8731430
67 + 8731363 = 8731430
109 + 8731321 = 8731430
181 + 8731249 = 8731430
199 + 8731231 = 8731430
229 + 8731201 = 8731430

Showing the first eight; more decompositions exist.
