Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464342, here are decompositions:

61 + 31464281 = 31464342
71 + 31464271 = 31464342
73 + 31464269 = 31464342
109 + 31464233 = 31464342
149 + 31464193 = 31464342
193 + 31464149 = 31464342
199 + 31464143 = 31464342
263 + 31464079 = 31464342

Showing the first eight; more decompositions exist.
