Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615726, here are decompositions:

3 + 8615723 = 8615726
19 + 8615707 = 8615726
73 + 8615653 = 8615726
103 + 8615623 = 8615726
139 + 8615587 = 8615726
199 + 8615527 = 8615726
337 + 8615389 = 8615726
349 + 8615377 = 8615726

Showing the first eight; more decompositions exist.
