Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482254, here are decompositions:

7 + 31482247 = 31482254
151 + 31482103 = 31482254
157 + 31482097 = 31482254
211 + 31482043 = 31482254
241 + 31482013 = 31482254
367 + 31481887 = 31482254
487 + 31481767 = 31482254
523 + 31481731 = 31482254

Showing the first eight; more decompositions exist.
