Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612450, here are decompositions:

59 + 31612391 = 31612450
137 + 31612313 = 31612450
173 + 31612277 = 31612450
227 + 31612223 = 31612450
251 + 31612199 = 31612450
509 + 31611941 = 31612450
557 + 31611893 = 31612450
599 + 31611851 = 31612450

Showing the first eight; more decompositions exist.
