Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462694, here are decompositions:

103 + 31462591 = 31462694
163 + 31462531 = 31462694
223 + 31462471 = 31462694
313 + 31462381 = 31462694
331 + 31462363 = 31462694
337 + 31462357 = 31462694
421 + 31462273 = 31462694
673 + 31462021 = 31462694

Showing the first eight; more decompositions exist.
