Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465022, here are decompositions:

19 + 31465003 = 31465022
31 + 31464991 = 31465022
139 + 31464883 = 31465022
241 + 31464781 = 31465022
313 + 31464709 = 31465022
373 + 31464649 = 31465022
541 + 31464481 = 31465022
571 + 31464451 = 31465022

Showing the first eight; more decompositions exist.
