Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573766, here are decompositions:

13 + 31573753 = 31573766
19 + 31573747 = 31573766
127 + 31573639 = 31573766
139 + 31573627 = 31573766
373 + 31573393 = 31573766
409 + 31573357 = 31573766
487 + 31573279 = 31573766
577 + 31573189 = 31573766

Showing the first eight; more decompositions exist.
