Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73780, here are decompositions:

23 + 73757 = 73780
29 + 73751 = 73780
53 + 73727 = 73780
59 + 73721 = 73780
71 + 73709 = 73780
101 + 73679 = 73780
107 + 73673 = 73780
137 + 73643 = 73780

Showing the first eight; more decompositions exist.
