Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543242, here are decompositions:

11 + 31543231 = 31543242
19 + 31543223 = 31543242
23 + 31543219 = 31543242
61 + 31543181 = 31543242
79 + 31543163 = 31543242
109 + 31543133 = 31543242
139 + 31543103 = 31543242
163 + 31543079 = 31543242

Showing the first eight; more decompositions exist.
