Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477022, here are decompositions:

151 + 31476871 = 31477022
193 + 31476829 = 31477022
223 + 31476799 = 31477022
331 + 31476691 = 31477022
523 + 31476499 = 31477022
571 + 31476451 = 31477022
631 + 31476391 = 31477022
673 + 31476349 = 31477022

Showing the first eight; more decompositions exist.
