Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504294, here are decompositions:

167 + 31504127 = 31504294
191 + 31504103 = 31504294
197 + 31504097 = 31504294
257 + 31504037 = 31504294
281 + 31504013 = 31504294
317 + 31503977 = 31504294
383 + 31503911 = 31504294
431 + 31503863 = 31504294

Showing the first eight; more decompositions exist.
