Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651042, here are decompositions:

3 + 8651039 = 8651042
61 + 8650981 = 8651042
163 + 8650879 = 8651042
193 + 8650849 = 8651042
229 + 8650813 = 8651042
373 + 8650669 = 8651042
409 + 8650633 = 8651042
613 + 8650429 = 8651042

Showing the first eight; more decompositions exist.
