Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513484, here are decompositions:

61 + 31513423 = 31513484
73 + 31513411 = 31513484
151 + 31513333 = 31513484
181 + 31513303 = 31513484
271 + 31513213 = 31513484
283 + 31513201 = 31513484
337 + 31513147 = 31513484
367 + 31513117 = 31513484

Showing the first eight; more decompositions exist.
