Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522090, here are decompositions:

29 + 31522061 = 31522090
71 + 31522019 = 31522090
113 + 31521977 = 31522090
137 + 31521953 = 31522090
227 + 31521863 = 31522090
239 + 31521851 = 31522090
419 + 31521671 = 31522090
443 + 31521647 = 31522090

Showing the first eight; more decompositions exist.
