Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51844, here are decompositions:
- 5 + 51839 = 51844
- 17 + 51827 = 51844
- 41 + 51803 = 51844
- 47 + 51797 = 51844
- 131 + 51713 = 51844
- 197 + 51647 = 51844
- 251 + 51593 = 51844
- 263 + 51581 = 51844
Showing the first eight; more decompositions exist.
