Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552082, here are decompositions:

13 + 31552069 = 31552082
103 + 31551979 = 31552082
181 + 31551901 = 31552082
223 + 31551859 = 31552082
229 + 31551853 = 31552082
349 + 31551733 = 31552082
631 + 31551451 = 31552082
673 + 31551409 = 31552082

Showing the first eight; more decompositions exist.
