Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731758, here are decompositions:

37 + 8731721 = 8731758
47 + 8731711 = 8731758
59 + 8731699 = 8731758
71 + 8731687 = 8731758
97 + 8731661 = 8731758
131 + 8731627 = 8731758
149 + 8731609 = 8731758
151 + 8731607 = 8731758

Showing the first eight; more decompositions exist.
