Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465626, here are decompositions:

7 + 31465619 = 31465626
47 + 31465579 = 31465626
79 + 31465547 = 31465626
97 + 31465529 = 31465626
167 + 31465459 = 31465626
263 + 31465363 = 31465626
317 + 31465309 = 31465626
337 + 31465289 = 31465626

Showing the first eight; more decompositions exist.
