Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613804, here are decompositions:

3 + 31613801 = 31613804
7 + 31613797 = 31613804
181 + 31613623 = 31613804
223 + 31613581 = 31613804
367 + 31613437 = 31613804
421 + 31613383 = 31613804
463 + 31613341 = 31613804
577 + 31613227 = 31613804

Showing the first eight; more decompositions exist.
