Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573004, here are decompositions:

61 + 31572943 = 31573004
103 + 31572901 = 31573004
163 + 31572841 = 31573004
181 + 31572823 = 31573004
241 + 31572763 = 31573004
271 + 31572733 = 31573004
277 + 31572727 = 31573004
367 + 31572637 = 31573004

Showing the first eight; more decompositions exist.
