Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616402, here are decompositions:

43 + 31616359 = 31616402
151 + 31616251 = 31616402
229 + 31616173 = 31616402
379 + 31616023 = 31616402
409 + 31615993 = 31616402
619 + 31615783 = 31616402
661 + 31615741 = 31616402
673 + 31615729 = 31616402

Showing the first eight; more decompositions exist.
