Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504396, here are decompositions:

23 + 31504373 = 31504396
29 + 31504367 = 31504396
167 + 31504229 = 31504396
263 + 31504133 = 31504396
269 + 31504127 = 31504396
293 + 31504103 = 31504396
359 + 31504037 = 31504396
383 + 31504013 = 31504396

Showing the first eight; more decompositions exist.
