Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740380, here are decompositions:
- 7 + 8740373 = 8740380
- 13 + 8740367 = 8740380
- 43 + 8740337 = 8740380
- 53 + 8740327 = 8740380
- 59 + 8740321 = 8740380
- 79 + 8740301 = 8740380
- 107 + 8740273 = 8740380
- 193 + 8740187 = 8740380
Showing the first eight; more decompositions exist.
