Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543228, here are decompositions:

5 + 31543223 = 31543228
11 + 31543217 = 31543228
47 + 31543181 = 31543228
149 + 31543079 = 31543228
257 + 31542971 = 31543228
317 + 31542911 = 31543228
347 + 31542881 = 31543228
401 + 31542827 = 31543228

Showing the first eight; more decompositions exist.
