Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513526, here are decompositions:

103 + 31513423 = 31513526
193 + 31513333 = 31513526
223 + 31513303 = 31513526
307 + 31513219 = 31513526
313 + 31513213 = 31513526
379 + 31513147 = 31513526
409 + 31513117 = 31513526
463 + 31513063 = 31513526

Showing the first eight; more decompositions exist.
