Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472766, here are decompositions:

43 + 31472723 = 31472766
67 + 31472699 = 31472766
97 + 31472669 = 31472766
103 + 31472663 = 31472766
179 + 31472587 = 31472766
229 + 31472537 = 31472766
277 + 31472489 = 31472766
317 + 31472449 = 31472766

Showing the first eight; more decompositions exist.
