Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543592, here are decompositions:

13 + 31543579 = 31543592
61 + 31543531 = 31543592
103 + 31543489 = 31543592
139 + 31543453 = 31543592
163 + 31543429 = 31543592
349 + 31543243 = 31543592
373 + 31543219 = 31543592
523 + 31543069 = 31543592

Showing the first eight; more decompositions exist.
