Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572026, here are decompositions:

19 + 31572007 = 31572026
43 + 31571983 = 31572026
127 + 31571899 = 31572026
139 + 31571887 = 31572026
193 + 31571833 = 31572026
223 + 31571803 = 31572026
373 + 31571653 = 31572026
379 + 31571647 = 31572026

Showing the first eight; more decompositions exist.
