Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28070, here are decompositions:
- 13 + 28057 = 28070
- 19 + 28051 = 28070
- 43 + 28027 = 28070
- 73 + 27997 = 28070
- 103 + 27967 = 28070
- 109 + 27961 = 28070
- 127 + 27943 = 28070
- 151 + 27919 = 28070
Showing the first eight; more decompositions exist.
