Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572134, here are decompositions:

3 + 31572131 = 31572134
127 + 31572007 = 31572134
151 + 31571983 = 31572134
313 + 31571821 = 31572134
331 + 31571803 = 31572134
487 + 31571647 = 31572134
523 + 31571611 = 31572134
577 + 31571557 = 31572134

Showing the first eight; more decompositions exist.
