Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494866, here are decompositions:

97 + 31494769 = 31494866
103 + 31494763 = 31494866
223 + 31494643 = 31494866
229 + 31494637 = 31494866
283 + 31494583 = 31494866
313 + 31494553 = 31494866
397 + 31494469 = 31494866
439 + 31494427 = 31494866

Showing the first eight; more decompositions exist.
