Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551364, here are decompositions:

3 + 31551361 = 31551364
11 + 31551353 = 31551364
17 + 31551347 = 31551364
23 + 31551341 = 31551364
83 + 31551281 = 31551364
191 + 31551173 = 31551364
227 + 31551137 = 31551364
293 + 31551071 = 31551364

Showing the first eight; more decompositions exist.
