Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528326, here are decompositions:

13 + 31528313 = 31528326
43 + 31528283 = 31528326
47 + 31528279 = 31528326
59 + 31528267 = 31528326
97 + 31528229 = 31528326
113 + 31528213 = 31528326
157 + 31528169 = 31528326
199 + 31528127 = 31528326

Showing the first eight; more decompositions exist.
