Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28010, here are decompositions:
- 13 + 27997 = 28010
- 43 + 27967 = 28010
- 67 + 27943 = 28010
- 109 + 27901 = 28010
- 127 + 27883 = 28010
- 163 + 27847 = 28010
- 193 + 27817 = 28010
- 211 + 27799 = 28010
Showing the first eight; more decompositions exist.
