Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45818, here are decompositions:
- 61 + 45757 = 45818
- 67 + 45751 = 45818
- 127 + 45691 = 45818
- 151 + 45667 = 45818
- 229 + 45589 = 45818
- 277 + 45541 = 45818
- 337 + 45481 = 45818
- 379 + 45439 = 45818
Showing the first eight; more decompositions exist.
