Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450536, here are decompositions:

53 + 31450483 = 31450536
107 + 31450429 = 31450536
109 + 31450427 = 31450536
113 + 31450423 = 31450536
127 + 31450409 = 31450536
149 + 31450387 = 31450536
167 + 31450369 = 31450536
223 + 31450313 = 31450536

Showing the first eight; more decompositions exist.
