Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534766, here are decompositions:

13 + 31534753 = 31534766
37 + 31534729 = 31534766
97 + 31534669 = 31534766
223 + 31534543 = 31534766
283 + 31534483 = 31534766
337 + 31534429 = 31534766
397 + 31534369 = 31534766
433 + 31534333 = 31534766

Showing the first eight; more decompositions exist.
