Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613032, here are decompositions:

5 + 31613027 = 31613032
41 + 31612991 = 31613032
71 + 31612961 = 31613032
179 + 31612853 = 31613032
293 + 31612739 = 31613032
443 + 31612589 = 31613032
449 + 31612583 = 31613032
641 + 31612391 = 31613032

Showing the first eight; more decompositions exist.
