Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503448, here are decompositions:

5 + 31503443 = 31503448
107 + 31503341 = 31503448
239 + 31503209 = 31503448
269 + 31503179 = 31503448
281 + 31503167 = 31503448
521 + 31502927 = 31503448
761 + 31502687 = 31503448
887 + 31502561 = 31503448

Showing the first eight; more decompositions exist.
