Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503396, here are decompositions:

17 + 31503379 = 31503396
53 + 31503343 = 31503396
59 + 31503337 = 31503396
73 + 31503323 = 31503396
83 + 31503313 = 31503396
137 + 31503259 = 31503396
167 + 31503229 = 31503396
179 + 31503217 = 31503396

Showing the first eight; more decompositions exist.
