Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460364, here are decompositions:

17 + 31460347 = 31460364
43 + 31460321 = 31460364
71 + 31460293 = 31460364
73 + 31460291 = 31460364
83 + 31460281 = 31460364
97 + 31460267 = 31460364
101 + 31460263 = 31460364
167 + 31460197 = 31460364

Showing the first eight; more decompositions exist.
