Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494302, here are decompositions:

61 + 31494241 = 31494302
211 + 31494091 = 31494302
223 + 31494079 = 31494302
313 + 31493989 = 31494302
421 + 31493881 = 31494302
523 + 31493779 = 31494302
613 + 31493689 = 31494302
661 + 31493641 = 31494302

Showing the first eight; more decompositions exist.
