Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462446, here are decompositions:

5 + 31462441 = 31462446
7 + 31462439 = 31462446
13 + 31462433 = 31462446
73 + 31462373 = 31462446
83 + 31462363 = 31462446
89 + 31462357 = 31462446
97 + 31462349 = 31462446
107 + 31462339 = 31462446

Showing the first eight; more decompositions exist.
