Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554702, here are decompositions:

31 + 31554671 = 31554702
43 + 31554659 = 31554702
61 + 31554641 = 31554702
71 + 31554631 = 31554702
83 + 31554619 = 31554702
89 + 31554613 = 31554702
131 + 31554571 = 31554702
163 + 31554539 = 31554702

Showing the first eight; more decompositions exist.
