Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534234, here are decompositions:

3 + 31534231 = 31534234
47 + 31534187 = 31534234
113 + 31534121 = 31534234
131 + 31534103 = 31534234
167 + 31534067 = 31534234
311 + 31533923 = 31534234
401 + 31533833 = 31534234
443 + 31533791 = 31534234

Showing the first eight; more decompositions exist.
