Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543126, here are decompositions:

23 + 31543103 = 31543126
47 + 31543079 = 31543126
59 + 31543067 = 31543126
107 + 31543019 = 31543126
269 + 31542857 = 31543126
317 + 31542809 = 31543126
359 + 31542767 = 31543126
449 + 31542677 = 31543126

Showing the first eight; more decompositions exist.
