Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503294, here are decompositions:

113 + 31503181 = 31503294
127 + 31503167 = 31503294
191 + 31503103 = 31503294
233 + 31503061 = 31503294
241 + 31503053 = 31503294
331 + 31502963 = 31503294
353 + 31502941 = 31503294
367 + 31502927 = 31503294

Showing the first eight; more decompositions exist.
