Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39428, here are decompositions:
- 19 + 39409 = 39428
- 31 + 39397 = 39428
- 61 + 39367 = 39428
- 127 + 39301 = 39428
- 199 + 39229 = 39428
- 211 + 39217 = 39428
- 229 + 39199 = 39428
- 271 + 39157 = 39428
Showing the first eight; more decompositions exist.
