Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462398, here are decompositions:

17 + 31462381 = 31462398
41 + 31462357 = 31462398
47 + 31462351 = 31462398
59 + 31462339 = 31462398
109 + 31462289 = 31462398
131 + 31462267 = 31462398
181 + 31462217 = 31462398
257 + 31462141 = 31462398

Showing the first eight; more decompositions exist.
