Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522002, here are decompositions:

11 + 31521991 = 31522002
23 + 31521979 = 31522002
139 + 31521863 = 31522002
151 + 31521851 = 31522002
173 + 31521829 = 31522002
263 + 31521739 = 31522002
331 + 31521671 = 31522002
353 + 31521649 = 31522002

Showing the first eight; more decompositions exist.
