Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731154, here are decompositions:

13 + 8731141 = 8731154
43 + 8731111 = 8731154
127 + 8731027 = 8731154
241 + 8730913 = 8731154
307 + 8730847 = 8731154
373 + 8730781 = 8731154
457 + 8730697 = 8731154
463 + 8730691 = 8731154

Showing the first eight; more decompositions exist.
