Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28612, here are decompositions:
- 5 + 28607 = 28612
- 41 + 28571 = 28612
- 53 + 28559 = 28612
- 71 + 28541 = 28612
- 113 + 28499 = 28612
- 149 + 28463 = 28612
- 173 + 28439 = 28612
- 179 + 28433 = 28612
Showing the first eight; more decompositions exist.
