Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61838, here are decompositions:
- 19 + 61819 = 61838
- 109 + 61729 = 61838
- 151 + 61687 = 61838
- 157 + 61681 = 61838
- 181 + 61657 = 61838
- 211 + 61627 = 61838
- 229 + 61609 = 61838
- 277 + 61561 = 61838
Showing the first eight; more decompositions exist.
