Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522506, here are decompositions:

13 + 31522493 = 31522506
47 + 31522459 = 31522506
73 + 31522433 = 31522506
149 + 31522357 = 31522506
167 + 31522339 = 31522506
179 + 31522327 = 31522506
193 + 31522313 = 31522506
229 + 31522277 = 31522506

Showing the first eight; more decompositions exist.
