Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494806, here are decompositions:

37 + 31494769 = 31494806
43 + 31494763 = 31494806
127 + 31494679 = 31494806
163 + 31494643 = 31494806
223 + 31494583 = 31494806
337 + 31494469 = 31494806
367 + 31494439 = 31494806
379 + 31494427 = 31494806

Showing the first eight; more decompositions exist.
