Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626860, here are decompositions:

3 + 31626857 = 31626860
19 + 31626841 = 31626860
73 + 31626787 = 31626860
151 + 31626709 = 31626860
193 + 31626667 = 31626860
241 + 31626619 = 31626860
271 + 31626589 = 31626860
313 + 31626547 = 31626860

Showing the first eight; more decompositions exist.
