Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495526, here are decompositions:

3 + 31495523 = 31495526
79 + 31495447 = 31495526
103 + 31495423 = 31495526
109 + 31495417 = 31495526
193 + 31495333 = 31495526
313 + 31495213 = 31495526
373 + 31495153 = 31495526
379 + 31495147 = 31495526

Showing the first eight; more decompositions exist.
