Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4628, here are decompositions:
- 7 + 4621 = 4628
- 31 + 4597 = 4628
- 37 + 4591 = 4628
- 61 + 4567 = 4628
- 67 + 4561 = 4628
- 79 + 4549 = 4628
- 109 + 4519 = 4628
- 181 + 4447 = 4628
Showing the first eight; more decompositions exist.
