Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503544, here are decompositions:

101 + 31503443 = 31503544
491 + 31503053 = 31503544
617 + 31502927 = 31503544
647 + 31502897 = 31503544
857 + 31502687 = 31503544
983 + 31502561 = 31503544
1061 + 31502483 = 31503544
1103 + 31502441 = 31503544

Showing the first eight; more decompositions exist.
