Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535966, here are decompositions:

19 + 31535947 = 31535966
139 + 31535827 = 31535966
157 + 31535809 = 31535966
373 + 31535593 = 31535966
463 + 31535503 = 31535966
499 + 31535467 = 31535966
547 + 31535419 = 31535966
733 + 31535233 = 31535966

Showing the first eight; more decompositions exist.
