Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495010, here are decompositions:

7 + 31495003 = 31495010
31 + 31494979 = 31495010
61 + 31494949 = 31495010
67 + 31494943 = 31495010
73 + 31494937 = 31495010
103 + 31494907 = 31495010
193 + 31494817 = 31495010
229 + 31494781 = 31495010

Showing the first eight; more decompositions exist.
