Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4742, here are decompositions:
- 13 + 4729 = 4742
- 19 + 4723 = 4742
- 79 + 4663 = 4742
- 103 + 4639 = 4742
- 139 + 4603 = 4742
- 151 + 4591 = 4742
- 181 + 4561 = 4742
- 193 + 4549 = 4742
Showing the first eight; more decompositions exist.
