Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495062, here are decompositions:

19 + 31495043 = 31495062
43 + 31495019 = 31495062
59 + 31495003 = 31495062
83 + 31494979 = 31495062
113 + 31494949 = 31495062
139 + 31494923 = 31495062
281 + 31494781 = 31495062
293 + 31494769 = 31495062

Showing the first eight; more decompositions exist.
