Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489714, here are decompositions:

5 + 31489709 = 31489714
41 + 31489673 = 31489714
101 + 31489613 = 31489714
173 + 31489541 = 31489714
251 + 31489463 = 31489714
281 + 31489433 = 31489714
467 + 31489247 = 31489714
521 + 31489193 = 31489714

Showing the first eight; more decompositions exist.
