Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64242, here are decompositions:
- 5 + 64237 = 64242
- 11 + 64231 = 64242
- 19 + 64223 = 64242
- 53 + 64189 = 64242
- 71 + 64171 = 64242
- 89 + 64153 = 64242
- 151 + 64091 = 64242
- 179 + 64063 = 64242
Showing the first eight; more decompositions exist.
