Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464742, here are decompositions:

11 + 31464731 = 31464742
41 + 31464701 = 31464742
233 + 31464509 = 31464742
383 + 31464359 = 31464742
401 + 31464341 = 31464742
461 + 31464281 = 31464742
509 + 31464233 = 31464742
593 + 31464149 = 31464742

Showing the first eight; more decompositions exist.
