Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543826, here are decompositions:

43 + 31543783 = 31543826
103 + 31543723 = 31543826
157 + 31543669 = 31543826
283 + 31543543 = 31543826
337 + 31543489 = 31543826
373 + 31543453 = 31543826
397 + 31543429 = 31543826
607 + 31543219 = 31543826

Showing the first eight; more decompositions exist.
