Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631242, here are decompositions:

13 + 8631229 = 8631242
43 + 8631199 = 8631242
241 + 8631001 = 8631242
271 + 8630971 = 8631242
313 + 8630929 = 8631242
409 + 8630833 = 8631242
421 + 8630821 = 8631242
463 + 8630779 = 8631242

Showing the first eight; more decompositions exist.
