Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460370, here are decompositions:

23 + 31460347 = 31460370
31 + 31460339 = 31460370
41 + 31460329 = 31460370
79 + 31460291 = 31460370
89 + 31460281 = 31460370
103 + 31460267 = 31460370
107 + 31460263 = 31460370
173 + 31460197 = 31460370

Showing the first eight; more decompositions exist.
