Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534364, here are decompositions:

31 + 31534333 = 31534364
67 + 31534297 = 31534364
181 + 31534183 = 31534364
223 + 31534141 = 31534364
307 + 31534057 = 31534364
313 + 31534051 = 31534364
331 + 31534033 = 31534364
397 + 31533967 = 31534364

Showing the first eight; more decompositions exist.
