Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503622, here are decompositions:

53 + 31503569 = 31503622
113 + 31503509 = 31503622
179 + 31503443 = 31503622
281 + 31503341 = 31503622
419 + 31503203 = 31503622
443 + 31503179 = 31503622
503 + 31503119 = 31503622
569 + 31503053 = 31503622

Showing the first eight; more decompositions exist.
