Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494068, here are decompositions:

79 + 31493989 = 31494068
127 + 31493941 = 31494068
211 + 31493857 = 31494068
379 + 31493689 = 31494068
457 + 31493611 = 31494068
499 + 31493569 = 31494068
547 + 31493521 = 31494068
601 + 31493467 = 31494068

Showing the first eight; more decompositions exist.
