Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731590, here are decompositions:

11 + 8731579 = 8731590
19 + 8731571 = 8731590
59 + 8731531 = 8731590
61 + 8731529 = 8731590
79 + 8731511 = 8731590
89 + 8731501 = 8731590
97 + 8731493 = 8731590
113 + 8731477 = 8731590

Showing the first eight; more decompositions exist.
