Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613792, here are decompositions:

73 + 31613719 = 31613792
163 + 31613629 = 31613792
211 + 31613581 = 31613792
241 + 31613551 = 31613792
409 + 31613383 = 31613792
601 + 31613191 = 31613792
673 + 31613119 = 31613792
739 + 31613053 = 31613792

Showing the first eight; more decompositions exist.
