Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494344, here are decompositions:

43 + 31494301 = 31494344
97 + 31494247 = 31494344
103 + 31494241 = 31494344
463 + 31493881 = 31494344
487 + 31493857 = 31494344
523 + 31493821 = 31494344
601 + 31493743 = 31494344
691 + 31493653 = 31494344

Showing the first eight; more decompositions exist.
