Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503360, here are decompositions:

17 + 31503343 = 31503360
19 + 31503341 = 31503360
23 + 31503337 = 31503360
29 + 31503331 = 31503360
37 + 31503323 = 31503360
47 + 31503313 = 31503360
101 + 31503259 = 31503360
131 + 31503229 = 31503360

Showing the first eight; more decompositions exist.
