Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456524, here are decompositions:

7 + 31456517 = 31456524
23 + 31456501 = 31456524
37 + 31456487 = 31456524
83 + 31456441 = 31456524
163 + 31456361 = 31456524
193 + 31456331 = 31456524
233 + 31456291 = 31456524
277 + 31456247 = 31456524

Showing the first eight; more decompositions exist.
