Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 132878, here are decompositions:
- 19 + 132859 = 132878
- 61 + 132817 = 132878
- 127 + 132751 = 132878
- 139 + 132739 = 132878
- 157 + 132721 = 132878
- 181 + 132697 = 132878
- 199 + 132679 = 132878
- 211 + 132667 = 132878
Showing the first eight; more decompositions exist.
