Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73820, here are decompositions:

37 + 73783 = 73820
127 + 73693 = 73820
139 + 73681 = 73820
211 + 73609 = 73820
223 + 73597 = 73820
337 + 73483 = 73820
349 + 73471 = 73820
367 + 73453 = 73820

Showing the first eight; more decompositions exist.
