Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573376, here are decompositions:

13 + 31573363 = 31573376
19 + 31573357 = 31573376
97 + 31573279 = 31573376
223 + 31573153 = 31573376
283 + 31573093 = 31573376
349 + 31573027 = 31573376
397 + 31572979 = 31573376
433 + 31572943 = 31573376

Showing the first eight; more decompositions exist.
