Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543802, here are decompositions:

19 + 31543783 = 31543802
79 + 31543723 = 31543802
223 + 31543579 = 31543802
271 + 31543531 = 31543802
313 + 31543489 = 31543802
349 + 31543453 = 31543802
373 + 31543429 = 31543802
571 + 31543231 = 31543802

Showing the first eight; more decompositions exist.
