Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22142, here are decompositions:
- 13 + 22129 = 22142
- 19 + 22123 = 22142
- 31 + 22111 = 22142
- 79 + 22063 = 22142
- 103 + 22039 = 22142
- 139 + 22003 = 22142
- 151 + 21991 = 22142
- 181 + 21961 = 22142
Showing the first eight; more decompositions exist.
