Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532346, here are decompositions:

5 + 31532341 = 31532346
7 + 31532339 = 31532346
17 + 31532329 = 31532346
23 + 31532323 = 31532346
67 + 31532279 = 31532346
127 + 31532219 = 31532346
137 + 31532209 = 31532346
179 + 31532167 = 31532346

Showing the first eight; more decompositions exist.
