Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55278, here are decompositions:
- 19 + 55259 = 55278
- 29 + 55249 = 55278
- 59 + 55219 = 55278
- 61 + 55217 = 55278
- 71 + 55207 = 55278
- 107 + 55171 = 55278
- 131 + 55147 = 55278
- 151 + 55127 = 55278
Showing the first eight; more decompositions exist.
