Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88138, here are decompositions:
- 59 + 88079 = 88138
- 101 + 88037 = 88138
- 131 + 88007 = 88138
- 137 + 88001 = 88138
- 179 + 87959 = 88138
- 227 + 87911 = 88138
- 251 + 87887 = 88138
- 257 + 87881 = 88138
Showing the first eight; more decompositions exist.
