Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496710, here are decompositions:

17 + 31496693 = 31496710
41 + 31496669 = 31496710
137 + 31496573 = 31496710
173 + 31496537 = 31496710
191 + 31496519 = 31496710
269 + 31496441 = 31496710
281 + 31496429 = 31496710
293 + 31496417 = 31496710

Showing the first eight; more decompositions exist.
