Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458050, here are decompositions:

37 + 31458013 = 31458050
61 + 31457989 = 31458050
139 + 31457911 = 31458050
181 + 31457869 = 31458050
193 + 31457857 = 31458050
229 + 31457821 = 31458050
307 + 31457743 = 31458050
313 + 31457737 = 31458050

Showing the first eight; more decompositions exist.
