Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535600, here are decompositions:

7 + 31535593 = 31535600
97 + 31535503 = 31535600
181 + 31535419 = 31535600
223 + 31535377 = 31535600
337 + 31535263 = 31535600
367 + 31535233 = 31535600
373 + 31535227 = 31535600
457 + 31535143 = 31535600

Showing the first eight; more decompositions exist.
