Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613704, here are decompositions:

191 + 31613513 = 31613704
263 + 31613441 = 31613704
293 + 31613411 = 31613704
347 + 31613357 = 31613704
461 + 31613243 = 31613704
587 + 31613117 = 31613704
677 + 31613027 = 31613704
743 + 31612961 = 31613704

Showing the first eight; more decompositions exist.
