Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573532, here are decompositions:

19 + 31573513 = 31573532
31 + 31573501 = 31573532
139 + 31573393 = 31573532
271 + 31573261 = 31573532
379 + 31573153 = 31573532
409 + 31573123 = 31573532
421 + 31573111 = 31573532
439 + 31573093 = 31573532

Showing the first eight; more decompositions exist.
