Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547762, here are decompositions:

13 + 31547749 = 31547762
31 + 31547731 = 31547762
61 + 31547701 = 31547762
79 + 31547683 = 31547762
223 + 31547539 = 31547762
283 + 31547479 = 31547762
313 + 31547449 = 31547762
349 + 31547413 = 31547762

Showing the first eight; more decompositions exist.
