Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464618, here are decompositions:

37 + 31464581 = 31464618
41 + 31464577 = 31464618
47 + 31464571 = 31464618
61 + 31464557 = 31464618
71 + 31464547 = 31464618
109 + 31464509 = 31464618
137 + 31464481 = 31464618
167 + 31464451 = 31464618

Showing the first eight; more decompositions exist.
