Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51628, here are decompositions:
- 29 + 51599 = 51628
- 47 + 51581 = 51628
- 89 + 51539 = 51628
- 107 + 51521 = 51628
- 149 + 51479 = 51628
- 167 + 51461 = 51628
- 179 + 51449 = 51628
- 191 + 51437 = 51628
Showing the first eight; more decompositions exist.
