Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573958, here are decompositions:

127 + 31573831 = 31573958
139 + 31573819 = 31573958
211 + 31573747 = 31573958
331 + 31573627 = 31573958
337 + 31573621 = 31573958
397 + 31573561 = 31573958
457 + 31573501 = 31573958
601 + 31573357 = 31573958

Showing the first eight; more decompositions exist.
