Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476450, here are decompositions:

13 + 31476437 = 31476450
17 + 31476433 = 31476450
37 + 31476413 = 31476450
59 + 31476391 = 31476450
67 + 31476383 = 31476450
79 + 31476371 = 31476450
97 + 31476353 = 31476450
101 + 31476349 = 31476450

Showing the first eight; more decompositions exist.
