Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528508, here are decompositions:

7 + 31528501 = 31528508
61 + 31528447 = 31528508
181 + 31528327 = 31528508
229 + 31528279 = 31528508
241 + 31528267 = 31528508
337 + 31528171 = 31528508
397 + 31528111 = 31528508
439 + 31528069 = 31528508

Showing the first eight; more decompositions exist.
