Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28038, here are decompositions:
- 7 + 28031 = 28038
- 11 + 28027 = 28038
- 19 + 28019 = 28038
- 37 + 28001 = 28038
- 41 + 27997 = 28038
- 71 + 27967 = 28038
- 97 + 27941 = 28038
- 137 + 27901 = 28038
Showing the first eight; more decompositions exist.
