Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543234, here are decompositions:

3 + 31543231 = 31543234
11 + 31543223 = 31543234
17 + 31543217 = 31543234
53 + 31543181 = 31543234
71 + 31543163 = 31543234
101 + 31543133 = 31543234
131 + 31543103 = 31543234
167 + 31543067 = 31543234

Showing the first eight; more decompositions exist.
