Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565234, here are decompositions:

3 + 31565231 = 31565234
13 + 31565221 = 31565234
37 + 31565197 = 31565234
61 + 31565173 = 31565234
67 + 31565167 = 31565234
157 + 31565077 = 31565234
193 + 31565041 = 31565234
307 + 31564927 = 31565234

Showing the first eight; more decompositions exist.
