Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539844, here are decompositions:

5 + 31539839 = 31539844
23 + 31539821 = 31539844
107 + 31539737 = 31539844
131 + 31539713 = 31539844
137 + 31539707 = 31539844
173 + 31539671 = 31539844
251 + 31539593 = 31539844
257 + 31539587 = 31539844

Showing the first eight; more decompositions exist.
