Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573826, here are decompositions:

3 + 31573823 = 31573826
7 + 31573819 = 31573826
73 + 31573753 = 31573826
79 + 31573747 = 31573826
199 + 31573627 = 31573826
313 + 31573513 = 31573826
433 + 31573393 = 31573826
463 + 31573363 = 31573826

Showing the first eight; more decompositions exist.
