Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494052, here are decompositions:

11 + 31494041 = 31494052
53 + 31493999 = 31494052
101 + 31493951 = 31494052
263 + 31493789 = 31494052
269 + 31493783 = 31494052
479 + 31493573 = 31494052
761 + 31493291 = 31494052
881 + 31493171 = 31494052

Showing the first eight; more decompositions exist.
