Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554968, here are decompositions:

7 + 31554961 = 31554968
19 + 31554949 = 31554968
79 + 31554889 = 31554968
127 + 31554841 = 31554968
139 + 31554829 = 31554968
157 + 31554811 = 31554968
229 + 31554739 = 31554968
331 + 31554637 = 31554968

Showing the first eight; more decompositions exist.
