Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495274, here are decompositions:

61 + 31495213 = 31495274
103 + 31495171 = 31495274
127 + 31495147 = 31495274
157 + 31495117 = 31495274
211 + 31495063 = 31495274
271 + 31495003 = 31495274
331 + 31494943 = 31495274
337 + 31494937 = 31495274

Showing the first eight; more decompositions exist.
