Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532776, here are decompositions:

83 + 31532693 = 31532776
89 + 31532687 = 31532776
137 + 31532639 = 31532776
179 + 31532597 = 31532776
269 + 31532507 = 31532776
347 + 31532429 = 31532776
557 + 31532219 = 31532776
659 + 31532117 = 31532776

Showing the first eight; more decompositions exist.
