Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465694, here are decompositions:

31 + 31465663 = 31465694
277 + 31465417 = 31465694
331 + 31465363 = 31465694
373 + 31465321 = 31465694
541 + 31465153 = 31465694
571 + 31465123 = 31465694
661 + 31465033 = 31465694
691 + 31465003 = 31465694

Showing the first eight; more decompositions exist.
