Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45198, here are decompositions:
- 7 + 45191 = 45198
- 17 + 45181 = 45198
- 19 + 45179 = 45198
- 37 + 45161 = 45198
- 59 + 45139 = 45198
- 61 + 45137 = 45198
- 67 + 45131 = 45198
- 71 + 45127 = 45198
Showing the first eight; more decompositions exist.
