Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503106, here are decompositions:

3 + 31503103 = 31503106
53 + 31503053 = 31503106
113 + 31502993 = 31503106
179 + 31502927 = 31503106
419 + 31502687 = 31503106
617 + 31502489 = 31503106
647 + 31502459 = 31503106
743 + 31502363 = 31503106

Showing the first eight; more decompositions exist.
