Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61100, here are decompositions:
- 43 + 61057 = 61100
- 73 + 61027 = 61100
- 139 + 60961 = 61100
- 157 + 60943 = 61100
- 163 + 60937 = 61100
- 181 + 60919 = 61100
- 199 + 60901 = 61100
- 211 + 60889 = 61100
Showing the first eight; more decompositions exist.
