Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28622, here are decompositions:
- 3 + 28619 = 28622
- 19 + 28603 = 28622
- 31 + 28591 = 28622
- 43 + 28579 = 28622
- 73 + 28549 = 28622
- 109 + 28513 = 28622
- 193 + 28429 = 28622
- 211 + 28411 = 28622
Showing the first eight; more decompositions exist.
