Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4992, here are decompositions:
- 5 + 4987 = 4992
- 19 + 4973 = 4992
- 23 + 4969 = 4992
- 41 + 4951 = 4992
- 59 + 4933 = 4992
- 61 + 4931 = 4992
- 73 + 4919 = 4992
- 83 + 4909 = 4992
Showing the first eight; more decompositions exist.
