Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131852, here are decompositions:
- 3 + 131849 = 131852
- 13 + 131839 = 131852
- 73 + 131779 = 131852
- 103 + 131749 = 131852
- 109 + 131743 = 131852
- 139 + 131713 = 131852
- 151 + 131701 = 131852
- 181 + 131671 = 131852
Showing the first eight; more decompositions exist.
