Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464222, here are decompositions:

29 + 31464193 = 31464222
73 + 31464149 = 31464222
79 + 31464143 = 31464222
191 + 31464031 = 31464222
263 + 31463959 = 31464222
281 + 31463941 = 31464222
311 + 31463911 = 31464222
313 + 31463909 = 31464222

Showing the first eight; more decompositions exist.
