Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38684, here are decompositions:
- 7 + 38677 = 38684
- 13 + 38671 = 38684
- 31 + 38653 = 38684
- 73 + 38611 = 38684
- 127 + 38557 = 38684
- 223 + 38461 = 38684
- 307 + 38377 = 38684
- 313 + 38371 = 38684
Showing the first eight; more decompositions exist.
