Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464358, here are decompositions:

17 + 31464341 = 31464358
89 + 31464269 = 31464358
311 + 31464047 = 31464358
449 + 31463909 = 31464358
461 + 31463897 = 31464358
467 + 31463891 = 31464358
479 + 31463879 = 31464358
509 + 31463849 = 31464358

Showing the first eight; more decompositions exist.
