Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51616, here are decompositions:
- 3 + 51613 = 51616
- 17 + 51599 = 51616
- 23 + 51593 = 51616
- 53 + 51563 = 51616
- 113 + 51503 = 51616
- 137 + 51479 = 51616
- 167 + 51449 = 51616
- 179 + 51437 = 51616
Showing the first eight; more decompositions exist.
