Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613484, here are decompositions:

43 + 31613441 = 31613484
47 + 31613437 = 31613484
73 + 31613411 = 31613484
83 + 31613401 = 31613484
101 + 31613383 = 31613484
107 + 31613377 = 31613484
127 + 31613357 = 31613484
151 + 31613333 = 31613484

Showing the first eight; more decompositions exist.
