Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476892, here are decompositions:

11 + 31476881 = 31476892
71 + 31476821 = 31476892
149 + 31476743 = 31476892
269 + 31476623 = 31476892
281 + 31476611 = 31476892
383 + 31476509 = 31476892
431 + 31476461 = 31476892
443 + 31476449 = 31476892

Showing the first eight; more decompositions exist.
