Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534634, here are decompositions:

3 + 31534631 = 31534634
37 + 31534597 = 31534634
73 + 31534561 = 31534634
151 + 31534483 = 31534634
193 + 31534441 = 31534634
211 + 31534423 = 31534634
223 + 31534411 = 31534634
337 + 31534297 = 31534634

Showing the first eight; more decompositions exist.
