Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522648, here are decompositions:

107 + 31522541 = 31522648
197 + 31522451 = 31522648
317 + 31522331 = 31522648
401 + 31522247 = 31522648
419 + 31522229 = 31522648
467 + 31522181 = 31522648
557 + 31522091 = 31522648
587 + 31522061 = 31522648

Showing the first eight; more decompositions exist.
