Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27390, here are decompositions:
- 23 + 27367 = 27390
- 29 + 27361 = 27390
- 53 + 27337 = 27390
- 61 + 27329 = 27390
- 107 + 27283 = 27390
- 109 + 27281 = 27390
- 113 + 27277 = 27390
- 131 + 27259 = 27390
Showing the first eight; more decompositions exist.
