Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554996, here are decompositions:

47 + 31554949 = 31554996
97 + 31554899 = 31554996
103 + 31554893 = 31554996
107 + 31554889 = 31554996
113 + 31554883 = 31554996
167 + 31554829 = 31554996
173 + 31554823 = 31554996
199 + 31554797 = 31554996

Showing the first eight; more decompositions exist.
