Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648590, here are decompositions:

47 + 8648543 = 8648590
53 + 8648537 = 8648590
59 + 8648531 = 8648590
89 + 8648501 = 8648590
131 + 8648459 = 8648590
257 + 8648333 = 8648590
479 + 8648111 = 8648590
491 + 8648099 = 8648590

Showing the first eight; more decompositions exist.
