Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573604, here are decompositions:

43 + 31573561 = 31573604
103 + 31573501 = 31573604
211 + 31573393 = 31573604
241 + 31573363 = 31573604
547 + 31573057 = 31573604
577 + 31573027 = 31573604
661 + 31572943 = 31573604
877 + 31572727 = 31573604

Showing the first eight; more decompositions exist.
