Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504456, here are decompositions:

3 + 31504453 = 31504456
17 + 31504439 = 31504456
83 + 31504373 = 31504456
89 + 31504367 = 31504456
227 + 31504229 = 31504456
353 + 31504103 = 31504456
359 + 31504097 = 31504456
419 + 31504037 = 31504456

Showing the first eight; more decompositions exist.
