Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532772, here are decompositions:

23 + 31532749 = 31532772
79 + 31532693 = 31532772
113 + 31532659 = 31532772
179 + 31532593 = 31532772
191 + 31532581 = 31532772
199 + 31532573 = 31532772
233 + 31532539 = 31532772
251 + 31532521 = 31532772

Showing the first eight; more decompositions exist.
