Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496752, here are decompositions:

11 + 31496741 = 31496752
59 + 31496693 = 31496752
83 + 31496669 = 31496752
179 + 31496573 = 31496752
233 + 31496519 = 31496752
263 + 31496489 = 31496752
311 + 31496441 = 31496752
383 + 31496369 = 31496752

Showing the first eight; more decompositions exist.
