Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53720, here are decompositions:

3 + 53717 = 53720
67 + 53653 = 53720
97 + 53623 = 53720
103 + 53617 = 53720
109 + 53611 = 53720
127 + 53593 = 53720
151 + 53569 = 53720
193 + 53527 = 53720

Showing the first eight; more decompositions exist.
