Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503526, here are decompositions:

17 + 31503509 = 31503526
83 + 31503443 = 31503526
317 + 31503209 = 31503526
347 + 31503179 = 31503526
359 + 31503167 = 31503526
419 + 31503107 = 31503526
563 + 31502963 = 31503526
599 + 31502927 = 31503526

Showing the first eight; more decompositions exist.
