Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456204, here are decompositions:

5 + 31456199 = 31456204
11 + 31456193 = 31456204
41 + 31456163 = 31456204
83 + 31456121 = 31456204
137 + 31456067 = 31456204
191 + 31456013 = 31456204
257 + 31455947 = 31456204
383 + 31455821 = 31456204

Showing the first eight; more decompositions exist.
