Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496824, here are decompositions:

5 + 31496819 = 31496824
41 + 31496783 = 31496824
83 + 31496741 = 31496824
131 + 31496693 = 31496824
251 + 31496573 = 31496824
257 + 31496567 = 31496824
383 + 31496441 = 31496824
503 + 31496321 = 31496824

Showing the first eight; more decompositions exist.
