Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25422, here are decompositions:
- 11 + 25411 = 25422
- 13 + 25409 = 25422
- 31 + 25391 = 25422
- 73 + 25349 = 25422
- 79 + 25343 = 25422
- 83 + 25339 = 25422
- 101 + 25321 = 25422
- 113 + 25309 = 25422
Showing the first eight; more decompositions exist.
