Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495058, here are decompositions:

79 + 31494979 = 31495058
109 + 31494949 = 31495058
139 + 31494919 = 31495058
151 + 31494907 = 31495058
241 + 31494817 = 31495058
277 + 31494781 = 31495058
337 + 31494721 = 31495058
367 + 31494691 = 31495058

Showing the first eight; more decompositions exist.
