Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450996, here are decompositions:

29 + 31450967 = 31450996
47 + 31450949 = 31450996
149 + 31450847 = 31450996
167 + 31450829 = 31450996
173 + 31450823 = 31450996
233 + 31450763 = 31450996
257 + 31450739 = 31450996
383 + 31450613 = 31450996

Showing the first eight; more decompositions exist.
