Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61238, here are decompositions:
- 7 + 61231 = 61238
- 97 + 61141 = 61238
- 109 + 61129 = 61238
- 139 + 61099 = 61238
- 181 + 61057 = 61238
- 211 + 61027 = 61238
- 277 + 60961 = 61238
- 337 + 60901 = 61238
Showing the first eight; more decompositions exist.
