Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482706, here are decompositions:

23 + 31482683 = 31482706
89 + 31482617 = 31482706
107 + 31482599 = 31482706
137 + 31482569 = 31482706
197 + 31482509 = 31482706
317 + 31482389 = 31482706
449 + 31482257 = 31482706
587 + 31482119 = 31482706

Showing the first eight; more decompositions exist.
