Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610844, here are decompositions:

53 + 31610791 = 31610844
71 + 31610773 = 31610844
73 + 31610771 = 31610844
103 + 31610741 = 31610844
137 + 31610707 = 31610844
257 + 31610587 = 31610844
263 + 31610581 = 31610844
271 + 31610573 = 31610844

Showing the first eight; more decompositions exist.
