Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503610, here are decompositions:

41 + 31503569 = 31503610
53 + 31503557 = 31503610
101 + 31503509 = 31503610
167 + 31503443 = 31503610
269 + 31503341 = 31503610
401 + 31503209 = 31503610
431 + 31503179 = 31503610
443 + 31503167 = 31503610

Showing the first eight; more decompositions exist.
