Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462386, here are decompositions:

5 + 31462381 = 31462386
13 + 31462373 = 31462386
23 + 31462363 = 31462386
29 + 31462357 = 31462386
37 + 31462349 = 31462386
47 + 31462339 = 31462386
73 + 31462313 = 31462386
97 + 31462289 = 31462386

Showing the first eight; more decompositions exist.
