Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476444, here are decompositions:

7 + 31476437 = 31476444
11 + 31476433 = 31476444
31 + 31476413 = 31476444
53 + 31476391 = 31476444
61 + 31476383 = 31476444
71 + 31476373 = 31476444
73 + 31476371 = 31476444
101 + 31476343 = 31476444

Showing the first eight; more decompositions exist.
