Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61158, here are decompositions:
- 5 + 61153 = 61158
- 7 + 61151 = 61158
- 17 + 61141 = 61158
- 29 + 61129 = 61158
- 37 + 61121 = 61158
- 59 + 61099 = 61158
- 67 + 61091 = 61158
- 101 + 61057 = 61158
Showing the first eight; more decompositions exist.
