Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694878, here are decompositions:

37 + 8694841 = 8694878
139 + 8694739 = 8694878
151 + 8694727 = 8694878
229 + 8694649 = 8694878
271 + 8694607 = 8694878
337 + 8694541 = 8694878
397 + 8694481 = 8694878
499 + 8694379 = 8694878

Showing the first eight; more decompositions exist.
