Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87132, here are decompositions:
- 11 + 87121 = 87132
- 13 + 87119 = 87132
- 29 + 87103 = 87132
- 61 + 87071 = 87132
- 83 + 87049 = 87132
- 139 + 86993 = 87132
- 151 + 86981 = 87132
- 163 + 86969 = 87132
Showing the first eight; more decompositions exist.
