Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613002, here are decompositions:

11 + 31612991 = 31613002
41 + 31612961 = 31613002
89 + 31612913 = 31613002
149 + 31612853 = 31613002
263 + 31612739 = 31613002
269 + 31612733 = 31613002
383 + 31612619 = 31613002
419 + 31612583 = 31613002

Showing the first eight; more decompositions exist.
