Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73128, here are decompositions:
- 7 + 73121 = 73128
- 37 + 73091 = 73128
- 67 + 73061 = 73128
- 89 + 73039 = 73128
- 109 + 73019 = 73128
- 131 + 72997 = 73128
- 151 + 72977 = 73128
- 179 + 72949 = 73128
Showing the first eight; more decompositions exist.
