Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476424, here are decompositions:

11 + 31476413 = 31476424
41 + 31476383 = 31476424
53 + 31476371 = 31476424
71 + 31476353 = 31476424
107 + 31476317 = 31476424
173 + 31476251 = 31476424
281 + 31476143 = 31476424
311 + 31476113 = 31476424

Showing the first eight; more decompositions exist.
