Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476982, here are decompositions:

23 + 31476959 = 31476982
101 + 31476881 = 31476982
239 + 31476743 = 31476982
359 + 31476623 = 31476982
389 + 31476593 = 31476982
431 + 31476551 = 31476982
521 + 31476461 = 31476982
569 + 31476413 = 31476982

Showing the first eight; more decompositions exist.
