Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61504, here are decompositions:
- 11 + 61493 = 61504
- 17 + 61487 = 61504
- 41 + 61463 = 61504
- 101 + 61403 = 61504
- 173 + 61331 = 61504
- 251 + 61253 = 61504
- 281 + 61223 = 61504
- 293 + 61211 = 61504
Showing the first eight; more decompositions exist.
