Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522950, here are decompositions:

13 + 31522937 = 31522950
61 + 31522889 = 31522950
103 + 31522847 = 31522950
127 + 31522823 = 31522950
233 + 31522717 = 31522950
257 + 31522693 = 31522950
281 + 31522669 = 31522950
293 + 31522657 = 31522950

Showing the first eight; more decompositions exist.
