Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657984, here are decompositions:

61 + 8657923 = 8657984
103 + 8657881 = 8657984
151 + 8657833 = 8657984
157 + 8657827 = 8657984
373 + 8657611 = 8657984
421 + 8657563 = 8657984
523 + 8657461 = 8657984
607 + 8657377 = 8657984

Showing the first eight; more decompositions exist.
