Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495302, here are decompositions:

29 + 31495273 = 31495302
61 + 31495241 = 31495302
89 + 31495213 = 31495302
103 + 31495199 = 31495302
131 + 31495171 = 31495302
149 + 31495153 = 31495302
193 + 31495109 = 31495302
239 + 31495063 = 31495302

Showing the first eight; more decompositions exist.
