Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513454, here are decompositions:

31 + 31513423 = 31513454
43 + 31513411 = 31513454
151 + 31513303 = 31513454
241 + 31513213 = 31513454
307 + 31513147 = 31513454
331 + 31513123 = 31513454
337 + 31513117 = 31513454
397 + 31513057 = 31513454

Showing the first eight; more decompositions exist.
