Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612572, here are decompositions:

41 + 31612531 = 31612572
59 + 31612513 = 31612572
149 + 31612423 = 31612572
181 + 31612391 = 31612572
191 + 31612381 = 31612572
263 + 31612309 = 31612572
331 + 31612241 = 31612572
349 + 31612223 = 31612572

Showing the first eight; more decompositions exist.
