Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573484, here are decompositions:

127 + 31573357 = 31573484
223 + 31573261 = 31573484
331 + 31573153 = 31573484
373 + 31573111 = 31573484
457 + 31573027 = 31573484
463 + 31573021 = 31573484
541 + 31572943 = 31573484
643 + 31572841 = 31573484

Showing the first eight; more decompositions exist.
