Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528544, here are decompositions:

13 + 31528531 = 31528544
43 + 31528501 = 31528544
97 + 31528447 = 31528544
181 + 31528363 = 31528544
277 + 31528267 = 31528544
331 + 31528213 = 31528544
337 + 31528207 = 31528544
373 + 31528171 = 31528544

Showing the first eight; more decompositions exist.
