Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482700, here are decompositions:

17 + 31482683 = 31482700
59 + 31482641 = 31482700
83 + 31482617 = 31482700
101 + 31482599 = 31482700
113 + 31482587 = 31482700
131 + 31482569 = 31482700
149 + 31482551 = 31482700
191 + 31482509 = 31482700

Showing the first eight; more decompositions exist.
