Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18752, here are decompositions:
- 3 + 18749 = 18752
- 61 + 18691 = 18752
- 73 + 18679 = 18752
- 199 + 18553 = 18752
- 211 + 18541 = 18752
- 229 + 18523 = 18752
- 271 + 18481 = 18752
- 313 + 18439 = 18752
Showing the first eight; more decompositions exist.
