Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5138, here are decompositions:
- 19 + 5119 = 5138
- 31 + 5107 = 5138
- 37 + 5101 = 5138
- 61 + 5077 = 5138
- 79 + 5059 = 5138
- 127 + 5011 = 5138
- 139 + 4999 = 5138
- 151 + 4987 = 5138
Showing the first eight; more decompositions exist.
