Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738572, here are decompositions:

5 + 8738567 = 8738572
173 + 8738399 = 8738572
233 + 8738339 = 8738572
239 + 8738333 = 8738572
443 + 8738129 = 8738572
449 + 8738123 = 8738572
593 + 8737979 = 8738572
701 + 8737871 = 8738572

Showing the first eight; more decompositions exist.
