Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51202, here are decompositions:
- 3 + 51199 = 51202
- 5 + 51197 = 51202
- 71 + 51131 = 51202
- 131 + 51071 = 51202
- 233 + 50969 = 51202
- 251 + 50951 = 51202
- 293 + 50909 = 51202
- 311 + 50891 = 51202
Showing the first eight; more decompositions exist.
