Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573652, here are decompositions:

13 + 31573639 = 31573652
31 + 31573621 = 31573652
139 + 31573513 = 31573652
151 + 31573501 = 31573652
373 + 31573279 = 31573652
463 + 31573189 = 31573652
499 + 31573153 = 31573652
541 + 31573111 = 31573652

Showing the first eight; more decompositions exist.
