Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494752, here are decompositions:

31 + 31494721 = 31494752
61 + 31494691 = 31494752
73 + 31494679 = 31494752
109 + 31494643 = 31494752
199 + 31494553 = 31494752
283 + 31494469 = 31494752
313 + 31494439 = 31494752
661 + 31494091 = 31494752

Showing the first eight; more decompositions exist.
