Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635572, here are decompositions:

5 + 8635567 = 8635572
13 + 8635559 = 8635572
19 + 8635553 = 8635572
41 + 8635531 = 8635572
59 + 8635513 = 8635572
103 + 8635469 = 8635572
131 + 8635441 = 8635572
139 + 8635433 = 8635572

Showing the first eight; more decompositions exist.
