Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36840, here are decompositions:

7 + 36833 = 36840
19 + 36821 = 36840
31 + 36809 = 36840
47 + 36793 = 36840
53 + 36787 = 36840
59 + 36781 = 36840
61 + 36779 = 36840
73 + 36767 = 36840

Showing the first eight; more decompositions exist.
