Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573862, here are decompositions:

3 + 31573859 = 31573862
31 + 31573831 = 31573862
43 + 31573819 = 31573862
109 + 31573753 = 31573862
223 + 31573639 = 31573862
241 + 31573621 = 31573862
349 + 31573513 = 31573862
499 + 31573363 = 31573862

Showing the first eight; more decompositions exist.
