Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527734, here are decompositions:

31 + 31527703 = 31527734
37 + 31527697 = 31527734
151 + 31527583 = 31527734
157 + 31527577 = 31527734
193 + 31527541 = 31527734
211 + 31527523 = 31527734
457 + 31527277 = 31527734
487 + 31527247 = 31527734

Showing the first eight; more decompositions exist.
