Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61128, here are decompositions:
- 7 + 61121 = 61128
- 29 + 61099 = 61128
- 37 + 61091 = 61128
- 71 + 61057 = 61128
- 97 + 61031 = 61128
- 101 + 61027 = 61128
- 127 + 61001 = 61128
- 167 + 60961 = 61128
Showing the first eight; more decompositions exist.
