Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522262, here are decompositions:

19 + 31522243 = 31522262
43 + 31522219 = 31522262
241 + 31522021 = 31522262
271 + 31521991 = 31522262
283 + 31521979 = 31522262
379 + 31521883 = 31522262
433 + 31521829 = 31522262
523 + 31521739 = 31522262

Showing the first eight; more decompositions exist.
