Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507562, here are decompositions:

103 + 31507459 = 31507562
199 + 31507363 = 31507562
211 + 31507351 = 31507562
241 + 31507321 = 31507562
613 + 31506949 = 31507562
631 + 31506931 = 31507562
733 + 31506829 = 31507562
739 + 31506823 = 31507562

Showing the first eight; more decompositions exist.
