Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462416, here are decompositions:

43 + 31462373 = 31462416
53 + 31462363 = 31462416
59 + 31462357 = 31462416
67 + 31462349 = 31462416
103 + 31462313 = 31462416
127 + 31462289 = 31462416
149 + 31462267 = 31462416
199 + 31462217 = 31462416

Showing the first eight; more decompositions exist.
