Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20238, here are decompositions:
- 5 + 20233 = 20238
- 7 + 20231 = 20238
- 19 + 20219 = 20238
- 37 + 20201 = 20238
- 61 + 20177 = 20238
- 89 + 20149 = 20238
- 109 + 20129 = 20238
- 131 + 20107 = 20238
Showing the first eight; more decompositions exist.
