Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532736, here are decompositions:

43 + 31532693 = 31532736
83 + 31532653 = 31532736
97 + 31532639 = 31532736
139 + 31532597 = 31532736
149 + 31532587 = 31532736
163 + 31532573 = 31532736
197 + 31532539 = 31532736
229 + 31532507 = 31532736

Showing the first eight; more decompositions exist.
