Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522202, here are decompositions:

73 + 31522129 = 31522202
181 + 31522021 = 31522202
211 + 31521991 = 31522202
223 + 31521979 = 31522202
373 + 31521829 = 31522202
409 + 31521793 = 31522202
463 + 31521739 = 31522202
631 + 31521571 = 31522202

Showing the first eight; more decompositions exist.
