Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45210, here are decompositions:
- 13 + 45197 = 45210
- 19 + 45191 = 45210
- 29 + 45181 = 45210
- 31 + 45179 = 45210
- 71 + 45139 = 45210
- 73 + 45137 = 45210
- 79 + 45131 = 45210
- 83 + 45127 = 45210
Showing the first eight; more decompositions exist.
