Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532802, here are decompositions:

53 + 31532749 = 31532802
109 + 31532693 = 31532802
149 + 31532653 = 31532802
163 + 31532639 = 31532802
229 + 31532573 = 31532802
251 + 31532551 = 31532802
263 + 31532539 = 31532802
281 + 31532521 = 31532802

Showing the first eight; more decompositions exist.
