Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540854, here are decompositions:

17 + 31540837 = 31540854
31 + 31540823 = 31540854
41 + 31540813 = 31540854
67 + 31540787 = 31540854
71 + 31540783 = 31540854
127 + 31540727 = 31540854
131 + 31540723 = 31540854
197 + 31540657 = 31540854

Showing the first eight; more decompositions exist.
