Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503670, here are decompositions:

101 + 31503569 = 31503670
113 + 31503557 = 31503670
227 + 31503443 = 31503670
347 + 31503323 = 31503670
461 + 31503209 = 31503670
467 + 31503203 = 31503670
491 + 31503179 = 31503670
503 + 31503167 = 31503670

Showing the first eight; more decompositions exist.
