Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573594, here are decompositions:

11 + 31573583 = 31573594
23 + 31573571 = 31573594
71 + 31573523 = 31573594
131 + 31573463 = 31573594
167 + 31573427 = 31573594
233 + 31573361 = 31573594
317 + 31573277 = 31573594
383 + 31573211 = 31573594

Showing the first eight; more decompositions exist.
