Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495270, here are decompositions:

29 + 31495241 = 31495270
71 + 31495199 = 31495270
83 + 31495187 = 31495270
113 + 31495157 = 31495270
227 + 31495043 = 31495270
251 + 31495019 = 31495270
347 + 31494923 = 31495270
383 + 31494887 = 31495270

Showing the first eight; more decompositions exist.
