Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61020, here are decompositions:
- 13 + 61007 = 61020
- 19 + 61001 = 61020
- 59 + 60961 = 61020
- 67 + 60953 = 61020
- 83 + 60937 = 61020
- 97 + 60923 = 61020
- 101 + 60919 = 61020
- 103 + 60917 = 61020
Showing the first eight; more decompositions exist.
