Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573000, here are decompositions:

29 + 31572971 = 31573000
59 + 31572941 = 31573000
131 + 31572869 = 31573000
191 + 31572809 = 31573000
269 + 31572731 = 31573000
353 + 31572647 = 31573000
359 + 31572641 = 31573000
449 + 31572551 = 31573000

Showing the first eight; more decompositions exist.
