Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522550, here are decompositions:

109 + 31522441 = 31522550
139 + 31522411 = 31522550
193 + 31522357 = 31522550
211 + 31522339 = 31522550
223 + 31522327 = 31522550
307 + 31522243 = 31522550
331 + 31522219 = 31522550
421 + 31522129 = 31522550

Showing the first eight; more decompositions exist.
