Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573844, here are decompositions:

13 + 31573831 = 31573844
97 + 31573747 = 31573844
223 + 31573621 = 31573844
283 + 31573561 = 31573844
331 + 31573513 = 31573844
487 + 31573357 = 31573844
691 + 31573153 = 31573844
733 + 31573111 = 31573844

Showing the first eight; more decompositions exist.
