Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573382, here are decompositions:

19 + 31573363 = 31573382
103 + 31573279 = 31573382
193 + 31573189 = 31573382
229 + 31573153 = 31573382
271 + 31573111 = 31573382
433 + 31572949 = 31573382
439 + 31572943 = 31573382
541 + 31572841 = 31573382

Showing the first eight; more decompositions exist.
