Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554696, here are decompositions:

29 + 31554667 = 31554696
37 + 31554659 = 31554696
59 + 31554637 = 31554696
79 + 31554617 = 31554696
83 + 31554613 = 31554696
113 + 31554583 = 31554696
127 + 31554569 = 31554696
157 + 31554539 = 31554696

Showing the first eight; more decompositions exist.
