Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73720, here are decompositions:

11 + 73709 = 73720
41 + 73679 = 73720
47 + 73673 = 73720
83 + 73637 = 73720
107 + 73613 = 73720
113 + 73607 = 73720
131 + 73589 = 73720
137 + 73583 = 73720

Showing the first eight; more decompositions exist.
