Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161248, here are decompositions:
- 11 + 161237 = 161248
- 47 + 161201 = 161248
- 89 + 161159 = 161248
- 107 + 161141 = 161248
- 239 + 161009 = 161248
- 251 + 160997 = 161248
- 281 + 160967 = 161248
- 419 + 160829 = 161248
Showing the first eight; more decompositions exist.
