Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45390, here are decompositions:
- 13 + 45377 = 45390
- 29 + 45361 = 45390
- 47 + 45343 = 45390
- 53 + 45337 = 45390
- 61 + 45329 = 45390
- 71 + 45319 = 45390
- 73 + 45317 = 45390
- 83 + 45307 = 45390
Showing the first eight; more decompositions exist.
