Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460358, here are decompositions:

11 + 31460347 = 31460358
19 + 31460339 = 31460358
29 + 31460329 = 31460358
37 + 31460321 = 31460358
67 + 31460291 = 31460358
79 + 31460279 = 31460358
191 + 31460167 = 31460358
229 + 31460129 = 31460358

Showing the first eight; more decompositions exist.
