Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522182, here are decompositions:

53 + 31522129 = 31522182
79 + 31522103 = 31522182
163 + 31522019 = 31522182
191 + 31521991 = 31522182
229 + 31521953 = 31522182
331 + 31521851 = 31522182
353 + 31521829 = 31522182
389 + 31521793 = 31522182

Showing the first eight; more decompositions exist.
