Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462396, here are decompositions:

23 + 31462373 = 31462396
47 + 31462349 = 31462396
83 + 31462313 = 31462396
107 + 31462289 = 31462396
179 + 31462217 = 31462396
263 + 31462133 = 31462396
269 + 31462127 = 31462396
293 + 31462103 = 31462396

Showing the first eight; more decompositions exist.
