Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476472, here are decompositions:

11 + 31476461 = 31476472
23 + 31476449 = 31476472
59 + 31476413 = 31476472
89 + 31476383 = 31476472
101 + 31476371 = 31476472
233 + 31476239 = 31476472
353 + 31476119 = 31476472
359 + 31476113 = 31476472

Showing the first eight; more decompositions exist.
