Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554654, here are decompositions:

13 + 31554641 = 31554654
17 + 31554637 = 31554654
23 + 31554631 = 31554654
37 + 31554617 = 31554654
41 + 31554613 = 31554654
71 + 31554583 = 31554654
83 + 31554571 = 31554654
113 + 31554541 = 31554654

Showing the first eight; more decompositions exist.
