Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22478, here are decompositions:
- 31 + 22447 = 22478
- 37 + 22441 = 22478
- 97 + 22381 = 22478
- 109 + 22369 = 22478
- 199 + 22279 = 22478
- 307 + 22171 = 22478
- 331 + 22147 = 22478
- 349 + 22129 = 22478
Showing the first eight; more decompositions exist.
