Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554924, here are decompositions:

31 + 31554893 = 31554924
41 + 31554883 = 31554924
61 + 31554863 = 31554924
73 + 31554851 = 31554924
83 + 31554841 = 31554924
101 + 31554823 = 31554924
113 + 31554811 = 31554924
127 + 31554797 = 31554924

Showing the first eight; more decompositions exist.
