Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482726, here are decompositions:

17 + 31482709 = 31482726
19 + 31482707 = 31482726
43 + 31482683 = 31482726
59 + 31482667 = 31482726
83 + 31482643 = 31482726
109 + 31482617 = 31482726
113 + 31482613 = 31482726
127 + 31482599 = 31482726

Showing the first eight; more decompositions exist.
