Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465826, here are decompositions:

37 + 31465789 = 31465826
79 + 31465747 = 31465826
163 + 31465663 = 31465826
367 + 31465459 = 31465826
409 + 31465417 = 31465826
463 + 31465363 = 31465826
643 + 31465183 = 31465826
673 + 31465153 = 31465826

Showing the first eight; more decompositions exist.
