Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543846, here are decompositions:

3 + 31543843 = 31543846
17 + 31543829 = 31543846
29 + 31543817 = 31543846
83 + 31543763 = 31543846
149 + 31543697 = 31543846
317 + 31543529 = 31543846
449 + 31543397 = 31543846
683 + 31543163 = 31543846

Showing the first eight; more decompositions exist.
