Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504366, here are decompositions:

137 + 31504229 = 31504366
233 + 31504133 = 31504366
239 + 31504127 = 31504366
263 + 31504103 = 31504366
269 + 31504097 = 31504366
353 + 31504013 = 31504366
389 + 31503977 = 31504366
449 + 31503917 = 31504366

Showing the first eight; more decompositions exist.
