Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55272, here are decompositions:
- 13 + 55259 = 55272
- 23 + 55249 = 55272
- 29 + 55243 = 55272
- 43 + 55229 = 55272
- 53 + 55219 = 55272
- 59 + 55213 = 55272
- 71 + 55201 = 55272
- 101 + 55171 = 55272
Showing the first eight; more decompositions exist.
