Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53172, here are decompositions:
- 11 + 53161 = 53172
- 23 + 53149 = 53172
- 43 + 53129 = 53172
- 59 + 53113 = 53172
- 71 + 53101 = 53172
- 79 + 53093 = 53172
- 83 + 53089 = 53172
- 103 + 53069 = 53172
Showing the first eight; more decompositions exist.
