Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550968, here are decompositions:

47 + 31550921 = 31550968
89 + 31550879 = 31550968
101 + 31550867 = 31550968
131 + 31550837 = 31550968
167 + 31550801 = 31550968
257 + 31550711 = 31550968
269 + 31550699 = 31550968
431 + 31550537 = 31550968

Showing the first eight; more decompositions exist.
