Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465664, here are decompositions:

3 + 31465661 = 31465664
103 + 31465561 = 31465664
421 + 31465243 = 31465664
487 + 31465177 = 31465664
541 + 31465123 = 31465664
631 + 31465033 = 31465664
661 + 31465003 = 31465664
673 + 31464991 = 31465664

Showing the first eight; more decompositions exist.
