Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446, here are decompositions:

53 + 31393 = 31446
59 + 31387 = 31446
67 + 31379 = 31446
89 + 31357 = 31446
109 + 31337 = 31446
113 + 31333 = 31446
127 + 31319 = 31446
139 + 31307 = 31446

Showing the first eight; more decompositions exist.
