Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61308, here are decompositions:
- 11 + 61297 = 61308
- 17 + 61291 = 61308
- 47 + 61261 = 61308
- 97 + 61211 = 61308
- 139 + 61169 = 61308
- 157 + 61151 = 61308
- 167 + 61141 = 61308
- 179 + 61129 = 61308
Showing the first eight; more decompositions exist.
