Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464282, here are decompositions:

11 + 31464271 = 31464282
13 + 31464269 = 31464282
89 + 31464193 = 31464282
139 + 31464143 = 31464282
251 + 31464031 = 31464282
281 + 31464001 = 31464282
373 + 31463909 = 31464282
389 + 31463893 = 31464282

Showing the first eight; more decompositions exist.
