Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532732, here are decompositions:

73 + 31532659 = 31532732
79 + 31532653 = 31532732
139 + 31532593 = 31532732
151 + 31532581 = 31532732
181 + 31532551 = 31532732
193 + 31532539 = 31532732
211 + 31532521 = 31532732
331 + 31532401 = 31532732

Showing the first eight; more decompositions exist.
