Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573562, here are decompositions:

3 + 31573559 = 31573562
61 + 31573501 = 31573562
199 + 31573363 = 31573562
283 + 31573279 = 31573562
373 + 31573189 = 31573562
409 + 31573153 = 31573562
439 + 31573123 = 31573562
541 + 31573021 = 31573562

Showing the first eight; more decompositions exist.
