Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476648, here are decompositions:

17 + 31476631 = 31476648
37 + 31476611 = 31476648
41 + 31476607 = 31476648
61 + 31476587 = 31476648
97 + 31476551 = 31476648
101 + 31476547 = 31476648
131 + 31476517 = 31476648
139 + 31476509 = 31476648

Showing the first eight; more decompositions exist.
