Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505522, here are decompositions:

3 + 31505519 = 31505522
79 + 31505443 = 31505522
151 + 31505371 = 31505522
163 + 31505359 = 31505522
193 + 31505329 = 31505522
229 + 31505293 = 31505522
379 + 31505143 = 31505522
523 + 31504999 = 31505522

Showing the first eight; more decompositions exist.
