Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573244, here are decompositions:

151 + 31573093 = 31573244
223 + 31573021 = 31573244
421 + 31572823 = 31573244
607 + 31572637 = 31573244
673 + 31572571 = 31573244
733 + 31572511 = 31573244
991 + 31572253 = 31573244
1021 + 31572223 = 31573244

Showing the first eight; more decompositions exist.
