Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464886, here are decompositions:

3 + 31464883 = 31464886
59 + 31464827 = 31464886
269 + 31464617 = 31464886
443 + 31464443 = 31464886
617 + 31464269 = 31464886
653 + 31464233 = 31464886
743 + 31464143 = 31464886
839 + 31464047 = 31464886

Showing the first eight; more decompositions exist.
