Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543766, here are decompositions:

3 + 31543763 = 31543766
43 + 31543723 = 31543766
97 + 31543669 = 31543766
223 + 31543543 = 31543766
277 + 31543489 = 31543766
313 + 31543453 = 31543766
337 + 31543429 = 31543766
523 + 31543243 = 31543766

Showing the first eight; more decompositions exist.
