Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495544, here are decompositions:

43 + 31495501 = 31495544
97 + 31495447 = 31495544
127 + 31495417 = 31495544
193 + 31495351 = 31495544
211 + 31495333 = 31495544
271 + 31495273 = 31495544
331 + 31495213 = 31495544
373 + 31495171 = 31495544

Showing the first eight; more decompositions exist.
