Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496548, here are decompositions:

11 + 31496537 = 31496548
29 + 31496519 = 31496548
59 + 31496489 = 31496548
107 + 31496441 = 31496548
131 + 31496417 = 31496548
179 + 31496369 = 31496548
227 + 31496321 = 31496548
449 + 31496099 = 31496548

Showing the first eight; more decompositions exist.
