Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454322, here are decompositions:

59 + 31454263 = 31454322
73 + 31454249 = 31454322
101 + 31454221 = 31454322
103 + 31454219 = 31454322
131 + 31454191 = 31454322
173 + 31454149 = 31454322
199 + 31454123 = 31454322
239 + 31454083 = 31454322

Showing the first eight; more decompositions exist.
