Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576476, here are decompositions:

17 + 31576459 = 31576476
23 + 31576453 = 31576476
37 + 31576439 = 31576476
59 + 31576417 = 31576476
67 + 31576409 = 31576476
73 + 31576403 = 31576476
103 + 31576373 = 31576476
109 + 31576367 = 31576476

Showing the first eight; more decompositions exist.
