Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523732, here are decompositions:

73 + 31523659 = 31523732
193 + 31523539 = 31523732
211 + 31523521 = 31523732
271 + 31523461 = 31523732
313 + 31523419 = 31523732
439 + 31523293 = 31523732
523 + 31523209 = 31523732
571 + 31523161 = 31523732

Showing the first eight; more decompositions exist.
