Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84390, here are decompositions:
- 13 + 84377 = 84390
- 41 + 84349 = 84390
- 43 + 84347 = 84390
- 71 + 84319 = 84390
- 73 + 84317 = 84390
- 83 + 84307 = 84390
- 127 + 84263 = 84390
- 151 + 84239 = 84390
Showing the first eight; more decompositions exist.
