Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464996, here are decompositions:

5 + 31464991 = 31464996
23 + 31464973 = 31464996
29 + 31464967 = 31464996
113 + 31464883 = 31464996
239 + 31464757 = 31464996
347 + 31464649 = 31464996
379 + 31464617 = 31464996
419 + 31464577 = 31464996

Showing the first eight; more decompositions exist.
