Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460532, here are decompositions:

23 + 31460509 = 31460532
41 + 31460491 = 31460532
101 + 31460431 = 31460532
163 + 31460369 = 31460532
193 + 31460339 = 31460532
211 + 31460321 = 31460532
239 + 31460293 = 31460532
241 + 31460291 = 31460532

Showing the first eight; more decompositions exist.
