Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554708, here are decompositions:

37 + 31554671 = 31554708
41 + 31554667 = 31554708
67 + 31554641 = 31554708
71 + 31554637 = 31554708
89 + 31554619 = 31554708
137 + 31554571 = 31554708
139 + 31554569 = 31554708
167 + 31554541 = 31554708

Showing the first eight; more decompositions exist.
