Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61258, here are decompositions:
- 5 + 61253 = 61258
- 47 + 61211 = 61258
- 89 + 61169 = 61258
- 107 + 61151 = 61258
- 137 + 61121 = 61258
- 167 + 61091 = 61258
- 227 + 61031 = 61258
- 251 + 61007 = 61258
Showing the first eight; more decompositions exist.
