Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573394, here are decompositions:

3 + 31573391 = 31573394
31 + 31573363 = 31573394
37 + 31573357 = 31573394
241 + 31573153 = 31573394
271 + 31573123 = 31573394
283 + 31573111 = 31573394
337 + 31573057 = 31573394
367 + 31573027 = 31573394

Showing the first eight; more decompositions exist.
