Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522206, here are decompositions:

103 + 31522103 = 31522206
193 + 31522013 = 31522206
227 + 31521979 = 31522206
229 + 31521977 = 31522206
467 + 31521739 = 31522206
523 + 31521683 = 31522206
557 + 31521649 = 31522206
563 + 31521643 = 31522206

Showing the first eight; more decompositions exist.
