Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64402, here are decompositions:
- 3 + 64399 = 64402
- 29 + 64373 = 64402
- 83 + 64319 = 64402
- 101 + 64301 = 64402
- 131 + 64271 = 64402
- 179 + 64223 = 64402
- 251 + 64151 = 64402
- 293 + 64109 = 64402
Showing the first eight; more decompositions exist.
