Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462562, here are decompositions:

31 + 31462531 = 31462562
181 + 31462381 = 31462562
199 + 31462363 = 31462562
211 + 31462351 = 31462562
223 + 31462339 = 31462562
421 + 31462141 = 31462562
541 + 31462021 = 31462562
601 + 31461961 = 31462562

Showing the first eight; more decompositions exist.
