Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460458, here are decompositions:

17 + 31460441 = 31460458
59 + 31460399 = 31460458
89 + 31460369 = 31460458
137 + 31460321 = 31460458
167 + 31460291 = 31460458
179 + 31460279 = 31460458
191 + 31460267 = 31460458
509 + 31459949 = 31460458

Showing the first eight; more decompositions exist.
