Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537004, here are decompositions:

3 + 31537001 = 31537004
13 + 31536991 = 31537004
61 + 31536943 = 31537004
67 + 31536937 = 31537004
157 + 31536847 = 31537004
181 + 31536823 = 31537004
211 + 31536793 = 31537004
271 + 31536733 = 31537004

Showing the first eight; more decompositions exist.
