Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61420, here are decompositions:
- 3 + 61417 = 61420
- 11 + 61409 = 61420
- 17 + 61403 = 61420
- 41 + 61379 = 61420
- 89 + 61331 = 61420
- 137 + 61283 = 61420
- 167 + 61253 = 61420
- 197 + 61223 = 61420
Showing the first eight; more decompositions exist.
