Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613380, here are decompositions:

31 + 8613349 = 8613380
151 + 8613229 = 8613380
199 + 8613181 = 8613380
337 + 8613043 = 8613380
379 + 8613001 = 8613380
397 + 8612983 = 8613380
421 + 8612959 = 8613380
439 + 8612941 = 8613380

Showing the first eight; more decompositions exist.
