Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486322, here are decompositions:

19 + 31486303 = 31486322
193 + 31486129 = 31486322
199 + 31486123 = 31486322
313 + 31486009 = 31486322
349 + 31485973 = 31486322
433 + 31485889 = 31486322
499 + 31485823 = 31486322
523 + 31485799 = 31486322

Showing the first eight; more decompositions exist.
