Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61180, here are decompositions:
- 11 + 61169 = 61180
- 29 + 61151 = 61180
- 59 + 61121 = 61180
- 89 + 61091 = 61180
- 137 + 61043 = 61180
- 149 + 61031 = 61180
- 173 + 61007 = 61180
- 179 + 61001 = 61180
Showing the first eight; more decompositions exist.
