Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494854, here are decompositions:

37 + 31494817 = 31494854
73 + 31494781 = 31494854
163 + 31494691 = 31494854
211 + 31494643 = 31494854
271 + 31494583 = 31494854
607 + 31494247 = 31494854
613 + 31494241 = 31494854
757 + 31494097 = 31494854

Showing the first eight; more decompositions exist.
