Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61290, here are decompositions:
- 7 + 61283 = 61290
- 29 + 61261 = 61290
- 37 + 61253 = 61290
- 59 + 61231 = 61290
- 67 + 61223 = 61290
- 79 + 61211 = 61290
- 137 + 61153 = 61290
- 139 + 61151 = 61290
Showing the first eight; more decompositions exist.
