Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482690, here are decompositions:

7 + 31482683 = 31482690
23 + 31482667 = 31482690
47 + 31482643 = 31482690
59 + 31482631 = 31482690
73 + 31482617 = 31482690
103 + 31482587 = 31482690
131 + 31482559 = 31482690
139 + 31482551 = 31482690

Showing the first eight; more decompositions exist.
