Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494746, here are decompositions:

67 + 31494679 = 31494746
103 + 31494643 = 31494746
109 + 31494637 = 31494746
163 + 31494583 = 31494746
193 + 31494553 = 31494746
277 + 31494469 = 31494746
307 + 31494439 = 31494746
499 + 31494247 = 31494746

Showing the first eight; more decompositions exist.
