Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545804, here are decompositions:

41 + 31545763 = 31545804
61 + 31545743 = 31545804
67 + 31545737 = 31545804
137 + 31545667 = 31545804
163 + 31545641 = 31545804
181 + 31545623 = 31545804
193 + 31545611 = 31545804
197 + 31545607 = 31545804

Showing the first eight; more decompositions exist.
