Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488422, here are decompositions:

151 + 31488271 = 31488422
211 + 31488211 = 31488422
313 + 31488109 = 31488422
331 + 31488091 = 31488422
409 + 31488013 = 31488422
619 + 31487803 = 31488422
643 + 31487779 = 31488422
883 + 31487539 = 31488422

Showing the first eight; more decompositions exist.
