Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465670, here are decompositions:

7 + 31465663 = 31465670
109 + 31465561 = 31465670
211 + 31465459 = 31465670
307 + 31465363 = 31465670
349 + 31465321 = 31465670
487 + 31465183 = 31465670
541 + 31465129 = 31465670
547 + 31465123 = 31465670

Showing the first eight; more decompositions exist.
