Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45380, here are decompositions:
- 3 + 45377 = 45380
- 19 + 45361 = 45380
- 37 + 45343 = 45380
- 43 + 45337 = 45380
- 61 + 45319 = 45380
- 73 + 45307 = 45380
- 199 + 45181 = 45380
- 241 + 45139 = 45380
Showing the first eight; more decompositions exist.
