Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87180, here are decompositions:
- 29 + 87151 = 87180
- 31 + 87149 = 87180
- 47 + 87133 = 87180
- 59 + 87121 = 87180
- 61 + 87119 = 87180
- 73 + 87107 = 87180
- 97 + 87083 = 87180
- 109 + 87071 = 87180
Showing the first eight; more decompositions exist.
