Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464472, here are decompositions:

29 + 31464443 = 31464472
71 + 31464401 = 31464472
113 + 31464359 = 31464472
131 + 31464341 = 31464472
191 + 31464281 = 31464472
239 + 31464233 = 31464472
509 + 31463963 = 31464472
563 + 31463909 = 31464472

Showing the first eight; more decompositions exist.
