Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522250, here are decompositions:

3 + 31522247 = 31522250
7 + 31522243 = 31522250
31 + 31522219 = 31522250
43 + 31522207 = 31522250
229 + 31522021 = 31522250
271 + 31521979 = 31522250
367 + 31521883 = 31522250
421 + 31521829 = 31522250

Showing the first eight; more decompositions exist.
