Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494836, here are decompositions:

19 + 31494817 = 31494836
67 + 31494769 = 31494836
73 + 31494763 = 31494836
157 + 31494679 = 31494836
193 + 31494643 = 31494836
199 + 31494637 = 31494836
283 + 31494553 = 31494836
367 + 31494469 = 31494836

Showing the first eight; more decompositions exist.
