Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616474, here are decompositions:

73 + 31616401 = 31616474
193 + 31616281 = 31616474
223 + 31616251 = 31616474
433 + 31616041 = 31616474
457 + 31616017 = 31616474
523 + 31615951 = 31616474
691 + 31615783 = 31616474
733 + 31615741 = 31616474

Showing the first eight; more decompositions exist.
