Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554982, here are decompositions:

83 + 31554899 = 31554982
89 + 31554893 = 31554982
131 + 31554851 = 31554982
191 + 31554791 = 31554982
233 + 31554749 = 31554982
311 + 31554671 = 31554982
443 + 31554539 = 31554982
509 + 31554473 = 31554982

Showing the first eight; more decompositions exist.
