Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619462, here are decompositions:

3 + 31619459 = 31619462
73 + 31619389 = 31619462
103 + 31619359 = 31619462
151 + 31619311 = 31619462
181 + 31619281 = 31619462
271 + 31619191 = 31619462
283 + 31619179 = 31619462
421 + 31619041 = 31619462

Showing the first eight; more decompositions exist.
