Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612000, here are decompositions:

3 + 31611997 = 31612000
59 + 31611941 = 31612000
83 + 31611917 = 31612000
89 + 31611911 = 31612000
107 + 31611893 = 31612000
131 + 31611869 = 31612000
149 + 31611851 = 31612000
197 + 31611803 = 31612000

Showing the first eight; more decompositions exist.
