Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464976, here are decompositions:

3 + 31464973 = 31464976
29 + 31464947 = 31464976
149 + 31464827 = 31464976
167 + 31464809 = 31464976
359 + 31464617 = 31464976
419 + 31464557 = 31464976
467 + 31464509 = 31464976
617 + 31464359 = 31464976

Showing the first eight; more decompositions exist.
