Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70380, here are decompositions:
- 7 + 70373 = 70380
- 29 + 70351 = 70380
- 53 + 70327 = 70380
- 59 + 70321 = 70380
- 67 + 70313 = 70380
- 71 + 70309 = 70380
- 83 + 70297 = 70380
- 109 + 70271 = 70380
Showing the first eight; more decompositions exist.
