Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55398, here are decompositions:
- 17 + 55381 = 55398
- 47 + 55351 = 55398
- 59 + 55339 = 55398
- 61 + 55337 = 55398
- 67 + 55331 = 55398
- 107 + 55291 = 55398
- 139 + 55259 = 55398
- 149 + 55249 = 55398
Showing the first eight; more decompositions exist.
