Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504354, here are decompositions:

3 + 31504351 = 31504354
227 + 31504127 = 31504354
251 + 31504103 = 31504354
257 + 31504097 = 31504354
317 + 31504037 = 31504354
383 + 31503971 = 31504354
443 + 31503911 = 31504354
467 + 31503887 = 31504354

Showing the first eight; more decompositions exist.
