Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494860, here are decompositions:

43 + 31494817 = 31494860
79 + 31494781 = 31494860
97 + 31494763 = 31494860
139 + 31494721 = 31494860
181 + 31494679 = 31494860
223 + 31494637 = 31494860
277 + 31494583 = 31494860
307 + 31494553 = 31494860

Showing the first eight; more decompositions exist.
