Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731778, here are decompositions:

67 + 8731711 = 8731778
79 + 8731699 = 8731778
151 + 8731627 = 8731778
199 + 8731579 = 8731778
277 + 8731501 = 8731778
331 + 8731447 = 8731778
397 + 8731381 = 8731778
409 + 8731369 = 8731778

Showing the first eight; more decompositions exist.
