Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522068, here are decompositions:

7 + 31522061 = 31522068
47 + 31522021 = 31522068
89 + 31521979 = 31522068
181 + 31521887 = 31522068
239 + 31521829 = 31522068
397 + 31521671 = 31522068
401 + 31521667 = 31522068
419 + 31521649 = 31522068

Showing the first eight; more decompositions exist.
