Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543526, here are decompositions:

37 + 31543489 = 31543526
73 + 31543453 = 31543526
97 + 31543429 = 31543526
283 + 31543243 = 31543526
307 + 31543219 = 31543526
457 + 31543069 = 31543526
577 + 31542949 = 31543526
727 + 31542799 = 31543526

Showing the first eight; more decompositions exist.
