Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535594, here are decompositions:

3 + 31535591 = 31535594
43 + 31535551 = 31535594
127 + 31535467 = 31535594
283 + 31535311 = 31535594
331 + 31535263 = 31535594
367 + 31535227 = 31535594
421 + 31535173 = 31535594
463 + 31535131 = 31535594

Showing the first eight; more decompositions exist.
