Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576204, here are decompositions:

3 + 31576201 = 31576204
5 + 31576199 = 31576204
17 + 31576187 = 31576204
41 + 31576163 = 31576204
83 + 31576121 = 31576204
113 + 31576091 = 31576204
137 + 31576067 = 31576204
167 + 31576037 = 31576204

Showing the first eight; more decompositions exist.
