Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503706, here are decompositions:

137 + 31503569 = 31503706
149 + 31503557 = 31503706
197 + 31503509 = 31503706
263 + 31503443 = 31503706
383 + 31503323 = 31503706
503 + 31503203 = 31503706
587 + 31503119 = 31503706
599 + 31503107 = 31503706

Showing the first eight; more decompositions exist.
