Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528598, here are decompositions:

19 + 31528579 = 31528598
67 + 31528531 = 31528598
97 + 31528501 = 31528598
139 + 31528459 = 31528598
151 + 31528447 = 31528598
271 + 31528327 = 31528598
307 + 31528291 = 31528598
331 + 31528267 = 31528598

Showing the first eight; more decompositions exist.
