Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464700, here are decompositions:

83 + 31464617 = 31464700
191 + 31464509 = 31464700
257 + 31464443 = 31464700
359 + 31464341 = 31464700
419 + 31464281 = 31464700
431 + 31464269 = 31464700
467 + 31464233 = 31464700
557 + 31464143 = 31464700

Showing the first eight; more decompositions exist.
