Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464952, here are decompositions:

5 + 31464947 = 31464952
11 + 31464941 = 31464952
131 + 31464821 = 31464952
251 + 31464701 = 31464952
443 + 31464509 = 31464952
509 + 31464443 = 31464952
593 + 31464359 = 31464952
683 + 31464269 = 31464952

Showing the first eight; more decompositions exist.
