Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450058, here are decompositions:

37 + 31450021 = 31450058
67 + 31449991 = 31450058
127 + 31449931 = 31450058
307 + 31449751 = 31450058
379 + 31449679 = 31450058
421 + 31449637 = 31450058
439 + 31449619 = 31450058
487 + 31449571 = 31450058

Showing the first eight; more decompositions exist.
