Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452364, here are decompositions:

23 + 31452341 = 31452364
131 + 31452233 = 31452364
191 + 31452173 = 31452364
227 + 31452137 = 31452364
233 + 31452131 = 31452364
557 + 31451807 = 31452364
563 + 31451801 = 31452364
641 + 31451723 = 31452364

Showing the first eight; more decompositions exist.
