Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450052, here are decompositions:

19 + 31450033 = 31450052
31 + 31450021 = 31450052
61 + 31449991 = 31450052
181 + 31449871 = 31450052
199 + 31449853 = 31450052
229 + 31449823 = 31450052
313 + 31449739 = 31450052
373 + 31449679 = 31450052

Showing the first eight; more decompositions exist.
