Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495194, here are decompositions:

7 + 31495187 = 31495194
23 + 31495171 = 31495194
37 + 31495157 = 31495194
41 + 31495153 = 31495194
47 + 31495147 = 31495194
131 + 31495063 = 31495194
151 + 31495043 = 31495194
191 + 31495003 = 31495194

Showing the first eight; more decompositions exist.
