Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535446, here are decompositions:

17 + 31535429 = 31535446
23 + 31535423 = 31535446
29 + 31535417 = 31535446
227 + 31535219 = 31535446
233 + 31535213 = 31535446
263 + 31535183 = 31535446
389 + 31535057 = 31535446
647 + 31534799 = 31535446

Showing the first eight; more decompositions exist.
