Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534340, here are decompositions:

7 + 31534333 = 31534340
43 + 31534297 = 31534340
109 + 31534231 = 31534340
157 + 31534183 = 31534340
199 + 31534141 = 31534340
223 + 31534117 = 31534340
283 + 31534057 = 31534340
307 + 31534033 = 31534340

Showing the first eight; more decompositions exist.
