Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731244, here are decompositions:

13 + 8731231 = 8731244
31 + 8731213 = 8731244
43 + 8731201 = 8731244
103 + 8731141 = 8731244
331 + 8730913 = 8731244
397 + 8730847 = 8731244
463 + 8730781 = 8731244
547 + 8730697 = 8731244

Showing the first eight; more decompositions exist.
