Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513364, here are decompositions:

31 + 31513333 = 31513364
61 + 31513303 = 31513364
151 + 31513213 = 31513364
163 + 31513201 = 31513364
241 + 31513123 = 31513364
307 + 31513057 = 31513364
331 + 31513033 = 31513364
367 + 31512997 = 31513364

Showing the first eight; more decompositions exist.
