Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540946, here are decompositions:

7 + 31540939 = 31540946
79 + 31540867 = 31540946
109 + 31540837 = 31540946
163 + 31540783 = 31540946
223 + 31540723 = 31540946
277 + 31540669 = 31540946
373 + 31540573 = 31540946
457 + 31540489 = 31540946

Showing the first eight; more decompositions exist.
