Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28046, here are decompositions:
- 19 + 28027 = 28046
- 79 + 27967 = 28046
- 103 + 27943 = 28046
- 127 + 27919 = 28046
- 163 + 27883 = 28046
- 199 + 27847 = 28046
- 223 + 27823 = 28046
- 229 + 27817 = 28046
Showing the first eight; more decompositions exist.
