Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73818, here are decompositions:

47 + 73771 = 73818
61 + 73757 = 73818
67 + 73751 = 73818
97 + 73721 = 73818
109 + 73709 = 73818
137 + 73681 = 73818
139 + 73679 = 73818
167 + 73651 = 73818

Showing the first eight; more decompositions exist.
