Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613080, here are decompositions:

53 + 31613027 = 31613080
89 + 31612991 = 31613080
167 + 31612913 = 31613080
227 + 31612853 = 31613080
347 + 31612733 = 31613080
353 + 31612727 = 31613080
419 + 31612661 = 31613080
461 + 31612619 = 31613080

Showing the first eight; more decompositions exist.
