Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462368, here are decompositions:

5 + 31462363 = 31462368
11 + 31462357 = 31462368
17 + 31462351 = 31462368
19 + 31462349 = 31462368
29 + 31462339 = 31462368
79 + 31462289 = 31462368
101 + 31462267 = 31462368
151 + 31462217 = 31462368

Showing the first eight; more decompositions exist.
