Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464648, here are decompositions:

29 + 31464619 = 31464648
31 + 31464617 = 31464648
67 + 31464581 = 31464648
71 + 31464577 = 31464648
101 + 31464547 = 31464648
139 + 31464509 = 31464648
167 + 31464481 = 31464648
197 + 31464451 = 31464648

Showing the first eight; more decompositions exist.
