Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503662, here are decompositions:

19 + 31503643 = 31503662
31 + 31503631 = 31503662
103 + 31503559 = 31503662
109 + 31503553 = 31503662
193 + 31503469 = 31503662
283 + 31503379 = 31503662
331 + 31503331 = 31503662
349 + 31503313 = 31503662

Showing the first eight; more decompositions exist.
