Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573460, here are decompositions:

67 + 31573393 = 31573460
97 + 31573363 = 31573460
103 + 31573357 = 31573460
181 + 31573279 = 31573460
199 + 31573261 = 31573460
271 + 31573189 = 31573460
307 + 31573153 = 31573460
337 + 31573123 = 31573460

Showing the first eight; more decompositions exist.
