Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115152, here are decompositions:
- 19 + 115133 = 115152
- 29 + 115123 = 115152
- 53 + 115099 = 115152
- 73 + 115079 = 115152
- 131 + 115021 = 115152
- 139 + 115013 = 115152
- 151 + 115001 = 115152
- 179 + 114973 = 115152
Showing the first eight; more decompositions exist.
