Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534946, here are decompositions:

67 + 31534879 = 31534946
73 + 31534873 = 31534946
127 + 31534819 = 31534946
193 + 31534753 = 31534946
277 + 31534669 = 31534946
349 + 31534597 = 31534946
463 + 31534483 = 31534946
523 + 31534423 = 31534946

Showing the first eight; more decompositions exist.
