Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618072, here are decompositions:

13 + 8618059 = 8618072
31 + 8618041 = 8618072
79 + 8617993 = 8618072
139 + 8617933 = 8618072
373 + 8617699 = 8618072
523 + 8617549 = 8618072
691 + 8617381 = 8618072
739 + 8617333 = 8618072

Showing the first eight; more decompositions exist.
