Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127624, here are decompositions:
- 17 + 127607 = 127624
- 23 + 127601 = 127624
- 41 + 127583 = 127624
- 83 + 127541 = 127624
- 131 + 127493 = 127624
- 137 + 127487 = 127624
- 251 + 127373 = 127624
- 281 + 127343 = 127624
Showing the first eight; more decompositions exist.
