Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545906, here are decompositions:

5 + 31545901 = 31545906
19 + 31545887 = 31545906
47 + 31545859 = 31545906
157 + 31545749 = 31545906
163 + 31545743 = 31545906
167 + 31545739 = 31545906
193 + 31545713 = 31545906
239 + 31545667 = 31545906

Showing the first eight; more decompositions exist.
