Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38258, here are decompositions:
- 19 + 38239 = 38258
- 61 + 38197 = 38258
- 109 + 38149 = 38258
- 139 + 38119 = 38258
- 211 + 38047 = 38258
- 271 + 37987 = 38258
- 307 + 37951 = 38258
- 379 + 37879 = 38258
Showing the first eight; more decompositions exist.
