Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5042, here are decompositions:
- 3 + 5039 = 5042
- 19 + 5023 = 5042
- 31 + 5011 = 5042
- 43 + 4999 = 5042
- 73 + 4969 = 5042
- 109 + 4933 = 5042
- 139 + 4903 = 5042
- 181 + 4861 = 5042
Showing the first eight; more decompositions exist.
