Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623778, here are decompositions:

61 + 8623717 = 8623778
127 + 8623651 = 8623778
139 + 8623639 = 8623778
157 + 8623621 = 8623778
199 + 8623579 = 8623778
349 + 8623429 = 8623778
421 + 8623357 = 8623778
439 + 8623339 = 8623778

Showing the first eight; more decompositions exist.
