Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61402, here are decompositions:
- 23 + 61379 = 61402
- 59 + 61343 = 61402
- 71 + 61331 = 61402
- 149 + 61253 = 61402
- 179 + 61223 = 61402
- 191 + 61211 = 61402
- 233 + 61169 = 61402
- 251 + 61151 = 61402
Showing the first eight; more decompositions exist.
