Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540848, here are decompositions:

11 + 31540837 = 31540848
61 + 31540787 = 31540848
139 + 31540709 = 31540848
149 + 31540699 = 31540848
179 + 31540669 = 31540848
191 + 31540657 = 31540848
197 + 31540651 = 31540848
211 + 31540637 = 31540848

Showing the first eight; more decompositions exist.
