Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464254, here are decompositions:

61 + 31464193 = 31464254
67 + 31464187 = 31464254
193 + 31464061 = 31464254
223 + 31464031 = 31464254
313 + 31463941 = 31464254
397 + 31463857 = 31464254
457 + 31463797 = 31464254
487 + 31463767 = 31464254

Showing the first eight; more decompositions exist.
