Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494992, here are decompositions:

13 + 31494979 = 31494992
43 + 31494949 = 31494992
73 + 31494919 = 31494992
211 + 31494781 = 31494992
223 + 31494769 = 31494992
229 + 31494763 = 31494992
271 + 31494721 = 31494992
313 + 31494679 = 31494992

Showing the first eight; more decompositions exist.
