Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90840, here are decompositions:

7 + 90833 = 90840
17 + 90823 = 90840
19 + 90821 = 90840
37 + 90803 = 90840
47 + 90793 = 90840
53 + 90787 = 90840
109 + 90731 = 90840
131 + 90709 = 90840

Showing the first eight; more decompositions exist.
