Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573424, here are decompositions:

31 + 31573393 = 31573424
61 + 31573363 = 31573424
67 + 31573357 = 31573424
163 + 31573261 = 31573424
271 + 31573153 = 31573424
313 + 31573111 = 31573424
331 + 31573093 = 31573424
367 + 31573057 = 31573424

Showing the first eight; more decompositions exist.
