Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5278, here are decompositions:
- 5 + 5273 = 5278
- 17 + 5261 = 5278
- 41 + 5237 = 5278
- 47 + 5231 = 5278
- 89 + 5189 = 5278
- 107 + 5171 = 5278
- 131 + 5147 = 5278
- 179 + 5099 = 5278
Showing the first eight; more decompositions exist.
