Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38730, here are decompositions:
- 7 + 38723 = 38730
- 17 + 38713 = 38730
- 19 + 38711 = 38730
- 23 + 38707 = 38730
- 31 + 38699 = 38730
- 37 + 38693 = 38730
- 53 + 38677 = 38730
- 59 + 38671 = 38730
Showing the first eight; more decompositions exist.
