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.
