Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462466, here are decompositions:

103 + 31462363 = 31462466
109 + 31462357 = 31462466
127 + 31462339 = 31462466
193 + 31462273 = 31462466
199 + 31462267 = 31462466
397 + 31462069 = 31462466
463 + 31462003 = 31462466
487 + 31461979 = 31462466

Showing the first eight; more decompositions exist.
