Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40890, here are decompositions:

7 + 40883 = 40890
11 + 40879 = 40890
23 + 40867 = 40890
37 + 40853 = 40890
41 + 40849 = 40890
43 + 40847 = 40890
61 + 40829 = 40890
67 + 40823 = 40890

Showing the first eight; more decompositions exist.
