Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61146, here are decompositions:
- 5 + 61141 = 61146
- 17 + 61129 = 61146
- 47 + 61099 = 61146
- 89 + 61057 = 61146
- 103 + 61043 = 61146
- 139 + 61007 = 61146
- 193 + 60953 = 61146
- 223 + 60923 = 61146
Showing the first eight; more decompositions exist.
