Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554948, here are decompositions:

59 + 31554889 = 31554948
97 + 31554851 = 31554948
107 + 31554841 = 31554948
137 + 31554811 = 31554948
151 + 31554797 = 31554948
157 + 31554791 = 31554948
199 + 31554749 = 31554948
239 + 31554709 = 31554948

Showing the first eight; more decompositions exist.
