Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637582, here are decompositions:

59 + 8637523 = 8637582
61 + 8637521 = 8637582
73 + 8637509 = 8637582
89 + 8637493 = 8637582
101 + 8637481 = 8637582
131 + 8637451 = 8637582
241 + 8637341 = 8637582
263 + 8637319 = 8637582

Showing the first eight; more decompositions exist.
