Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503148, here are decompositions:

29 + 31503119 = 31503148
41 + 31503107 = 31503148
251 + 31502897 = 31503148
449 + 31502699 = 31503148
461 + 31502687 = 31503148
587 + 31502561 = 31503148
659 + 31502489 = 31503148
1019 + 31502129 = 31503148

Showing the first eight; more decompositions exist.
