Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460394, here are decompositions:

47 + 31460347 = 31460394
73 + 31460321 = 31460394
101 + 31460293 = 31460394
103 + 31460291 = 31460394
113 + 31460281 = 31460394
127 + 31460267 = 31460394
131 + 31460263 = 31460394
197 + 31460197 = 31460394

Showing the first eight; more decompositions exist.
