Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117420, here are decompositions:
- 7 + 117413 = 117420
- 31 + 117389 = 117420
- 47 + 117373 = 117420
- 59 + 117361 = 117420
- 67 + 117353 = 117420
- 89 + 117331 = 117420
- 101 + 117319 = 117420
- 113 + 117307 = 117420
Showing the first eight; more decompositions exist.
