Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161132, here are decompositions:
- 61 + 161071 = 161132
- 73 + 161059 = 161132
- 79 + 161053 = 161132
- 151 + 160981 = 161132
- 163 + 160969 = 161132
- 199 + 160933 = 161132
- 229 + 160903 = 161132
- 271 + 160861 = 161132
Showing the first eight; more decompositions exist.
