Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506364, here are decompositions:

5 + 31506359 = 31506364
11 + 31506353 = 31506364
53 + 31506311 = 31506364
101 + 31506263 = 31506364
191 + 31506173 = 31506364
293 + 31506071 = 31506364
443 + 31505921 = 31506364
521 + 31505843 = 31506364

Showing the first eight; more decompositions exist.
