Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513496, here are decompositions:

73 + 31513423 = 31513496
163 + 31513333 = 31513496
193 + 31513303 = 31513496
277 + 31513219 = 31513496
283 + 31513213 = 31513496
349 + 31513147 = 31513496
373 + 31513123 = 31513496
379 + 31513117 = 31513496

Showing the first eight; more decompositions exist.
