Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535598, here are decompositions:

5 + 31535593 = 31535598
7 + 31535591 = 31535598
47 + 31535551 = 31535598
131 + 31535467 = 31535598
179 + 31535419 = 31535598
181 + 31535417 = 31535598
257 + 31535341 = 31535598
271 + 31535327 = 31535598

Showing the first eight; more decompositions exist.
