Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476394, here are decompositions:

3 + 31476391 = 31476394
11 + 31476383 = 31476394
23 + 31476371 = 31476394
41 + 31476353 = 31476394
251 + 31476143 = 31476394
281 + 31476113 = 31476394
431 + 31475963 = 31476394
617 + 31475777 = 31476394

Showing the first eight; more decompositions exist.
