Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495026, here are decompositions:

7 + 31495019 = 31495026
23 + 31495003 = 31495026
47 + 31494979 = 31495026
83 + 31494943 = 31495026
89 + 31494937 = 31495026
103 + 31494923 = 31495026
107 + 31494919 = 31495026
139 + 31494887 = 31495026

Showing the first eight; more decompositions exist.
