Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535602, here are decompositions:

11 + 31535591 = 31535602
53 + 31535549 = 31535602
173 + 31535429 = 31535602
179 + 31535423 = 31535602
191 + 31535411 = 31535602
281 + 31535321 = 31535602
383 + 31535219 = 31535602
389 + 31535213 = 31535602

Showing the first eight; more decompositions exist.
