Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30838, here are decompositions:
- 29 + 30809 = 30838
- 131 + 30707 = 30838
- 149 + 30689 = 30838
- 167 + 30671 = 30838
- 281 + 30557 = 30838
- 347 + 30491 = 30838
- 389 + 30449 = 30838
- 449 + 30389 = 30838
Showing the first eight; more decompositions exist.
