Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522370, here are decompositions:

7 + 31522363 = 31522370
13 + 31522357 = 31522370
31 + 31522339 = 31522370
43 + 31522327 = 31522370
73 + 31522297 = 31522370
127 + 31522243 = 31522370
151 + 31522219 = 31522370
163 + 31522207 = 31522370

Showing the first eight; more decompositions exist.
