Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476952, here are decompositions:

5 + 31476947 = 31476952
71 + 31476881 = 31476952
131 + 31476821 = 31476952
359 + 31476593 = 31476952
401 + 31476551 = 31476952
443 + 31476509 = 31476952
491 + 31476461 = 31476952
503 + 31476449 = 31476952

Showing the first eight; more decompositions exist.
