Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465358, here are decompositions:

37 + 31465321 = 31465358
181 + 31465177 = 31465358
229 + 31465129 = 31465358
367 + 31464991 = 31465358
571 + 31464787 = 31465358
577 + 31464781 = 31465358
601 + 31464757 = 31465358
709 + 31464649 = 31465358

Showing the first eight; more decompositions exist.
