Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458224, here are decompositions:

37 + 31458187 = 31458224
163 + 31458061 = 31458224
211 + 31458013 = 31458224
313 + 31457911 = 31458224
367 + 31457857 = 31458224
487 + 31457737 = 31458224
613 + 31457611 = 31458224
877 + 31457347 = 31458224

Showing the first eight; more decompositions exist.
