Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7430, here are decompositions:
- 13 + 7417 = 7430
- 19 + 7411 = 7430
- 37 + 7393 = 7430
- 61 + 7369 = 7430
- 79 + 7351 = 7430
- 97 + 7333 = 7430
- 109 + 7321 = 7430
- 193 + 7237 = 7430
Showing the first eight; more decompositions exist.
