Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22278, here are decompositions:
- 5 + 22273 = 22278
- 7 + 22271 = 22278
- 19 + 22259 = 22278
- 31 + 22247 = 22278
- 89 + 22189 = 22278
- 107 + 22171 = 22278
- 131 + 22147 = 22278
- 149 + 22129 = 22278
Showing the first eight; more decompositions exist.
