Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539010, here are decompositions:

3 + 31539007 = 31539010
23 + 31538987 = 31539010
59 + 31538951 = 31539010
257 + 31538753 = 31539010
281 + 31538729 = 31539010
317 + 31538693 = 31539010
431 + 31538579 = 31539010
449 + 31538561 = 31539010

Showing the first eight; more decompositions exist.
