Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532726, here are decompositions:

67 + 31532659 = 31532726
73 + 31532653 = 31532726
139 + 31532587 = 31532726
229 + 31532497 = 31532726
373 + 31532353 = 31532726
397 + 31532329 = 31532726
457 + 31532269 = 31532726
499 + 31532227 = 31532726

Showing the first eight; more decompositions exist.
