Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38478, here are decompositions:
- 17 + 38461 = 38478
- 19 + 38459 = 38478
- 29 + 38449 = 38478
- 31 + 38447 = 38478
- 47 + 38431 = 38478
- 101 + 38377 = 38478
- 107 + 38371 = 38478
- 127 + 38351 = 38478
Showing the first eight; more decompositions exist.
