Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590572, here are decompositions:

73 + 31590499 = 31590572
103 + 31590469 = 31590572
109 + 31590463 = 31590572
151 + 31590421 = 31590572
229 + 31590343 = 31590572
331 + 31590241 = 31590572
439 + 31590133 = 31590572
619 + 31589953 = 31590572

Showing the first eight; more decompositions exist.
