Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476844, here are decompositions:

23 + 31476821 = 31476844
101 + 31476743 = 31476844
233 + 31476611 = 31476844
251 + 31476593 = 31476844
257 + 31476587 = 31476844
293 + 31476551 = 31476844
383 + 31476461 = 31476844
431 + 31476413 = 31476844

Showing the first eight; more decompositions exist.
