Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61992, here are decompositions:
- 5 + 61987 = 61992
- 11 + 61981 = 61992
- 13 + 61979 = 61992
- 31 + 61961 = 61992
- 43 + 61949 = 61992
- 59 + 61933 = 61992
- 83 + 61909 = 61992
- 113 + 61879 = 61992
Showing the first eight; more decompositions exist.
