Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61390, here are decompositions:
- 11 + 61379 = 61390
- 47 + 61343 = 61390
- 59 + 61331 = 61390
- 107 + 61283 = 61390
- 137 + 61253 = 61390
- 167 + 61223 = 61390
- 179 + 61211 = 61390
- 239 + 61151 = 61390
Showing the first eight; more decompositions exist.
