Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45212, here are decompositions:
- 31 + 45181 = 45212
- 73 + 45139 = 45212
- 151 + 45061 = 45212
- 199 + 45013 = 45212
- 229 + 44983 = 45212
- 241 + 44971 = 45212
- 373 + 44839 = 45212
- 439 + 44773 = 45212
Showing the first eight; more decompositions exist.
