Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522404, here are decompositions:

31 + 31522373 = 31522404
41 + 31522363 = 31522404
47 + 31522357 = 31522404
73 + 31522331 = 31522404
107 + 31522297 = 31522404
127 + 31522277 = 31522404
157 + 31522247 = 31522404
163 + 31522241 = 31522404

Showing the first eight; more decompositions exist.
