Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508950, here are decompositions:

3 + 31508947 = 31508950
29 + 31508921 = 31508950
107 + 31508843 = 31508950
269 + 31508681 = 31508950
293 + 31508657 = 31508950
311 + 31508639 = 31508950
383 + 31508567 = 31508950
401 + 31508549 = 31508950

Showing the first eight; more decompositions exist.
