Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521076, here are decompositions:

23 + 31521053 = 31521076
47 + 31521029 = 31521076
179 + 31520897 = 31521076
239 + 31520837 = 31521076
449 + 31520627 = 31521076
557 + 31520519 = 31521076
593 + 31520483 = 31521076
659 + 31520417 = 31521076

Showing the first eight; more decompositions exist.
