Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724590, here are decompositions:

31 + 8724559 = 8724590
79 + 8724511 = 8724590
97 + 8724493 = 8724590
103 + 8724487 = 8724590
271 + 8724319 = 8724590
307 + 8724283 = 8724590
331 + 8724259 = 8724590
337 + 8724253 = 8724590

Showing the first eight; more decompositions exist.
