Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503340, here are decompositions:

3 + 31503337 = 31503340
17 + 31503323 = 31503340
131 + 31503209 = 31503340
137 + 31503203 = 31503340
173 + 31503167 = 31503340
233 + 31503107 = 31503340
347 + 31502993 = 31503340
443 + 31502897 = 31503340

Showing the first eight; more decompositions exist.
