Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535006, here are decompositions:

7 + 31534999 = 31535006
127 + 31534879 = 31535006
277 + 31534729 = 31535006
337 + 31534669 = 31535006
409 + 31534597 = 31535006
463 + 31534543 = 31535006
523 + 31534483 = 31535006
577 + 31534429 = 31535006

Showing the first eight; more decompositions exist.
