Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577004, here are decompositions:

13 + 31576991 = 31577004
37 + 31576967 = 31577004
47 + 31576957 = 31577004
73 + 31576931 = 31577004
103 + 31576901 = 31577004
113 + 31576891 = 31577004
227 + 31576777 = 31577004
331 + 31576673 = 31577004

Showing the first eight; more decompositions exist.
