Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493050, here are decompositions:

3 + 31493047 = 31493050
11 + 31493039 = 31493050
41 + 31493009 = 31493050
53 + 31492997 = 31493050
59 + 31492991 = 31493050
107 + 31492943 = 31493050
191 + 31492859 = 31493050
269 + 31492781 = 31493050

Showing the first eight; more decompositions exist.
