Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45242, here are decompositions:
- 61 + 45181 = 45242
- 103 + 45139 = 45242
- 181 + 45061 = 45242
- 229 + 45013 = 45242
- 271 + 44971 = 45242
- 283 + 44959 = 45242
- 349 + 44893 = 45242
- 433 + 44809 = 45242
Showing the first eight; more decompositions exist.
