Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574004, here are decompositions:

5 + 31573999 = 31574004
37 + 31573967 = 31574004
43 + 31573961 = 31574004
47 + 31573957 = 31574004
73 + 31573931 = 31574004
151 + 31573853 = 31574004
157 + 31573847 = 31574004
173 + 31573831 = 31574004

Showing the first eight; more decompositions exist.
