Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488022, here are decompositions:

3 + 31488019 = 31488022
29 + 31487993 = 31488022
149 + 31487873 = 31488022
239 + 31487783 = 31488022
359 + 31487663 = 31488022
479 + 31487543 = 31488022
509 + 31487513 = 31488022
641 + 31487381 = 31488022

Showing the first eight; more decompositions exist.
