Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503476, here are decompositions:

7 + 31503469 = 31503476
97 + 31503379 = 31503476
139 + 31503337 = 31503476
163 + 31503313 = 31503476
337 + 31503139 = 31503476
373 + 31503103 = 31503476
523 + 31502953 = 31503476
619 + 31502857 = 31503476

Showing the first eight; more decompositions exist.
