Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87152, here are decompositions:
- 3 + 87149 = 87152
- 19 + 87133 = 87152
- 31 + 87121 = 87152
- 103 + 87049 = 87152
- 139 + 87013 = 87152
- 193 + 86959 = 87152
- 223 + 86929 = 87152
- 229 + 86923 = 87152
Showing the first eight; more decompositions exist.
