Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462354, here are decompositions:

3 + 31462351 = 31462354
5 + 31462349 = 31462354
41 + 31462313 = 31462354
137 + 31462217 = 31462354
227 + 31462127 = 31462354
251 + 31462103 = 31462354
347 + 31462007 = 31462354
431 + 31461923 = 31462354

Showing the first eight; more decompositions exist.
