Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997430, here are decompositions:
- 3 + 997427 = 997430
- 61 + 997369 = 997430
- 73 + 997357 = 997430
- 97 + 997333 = 997430
- 103 + 997327 = 997430
- 151 + 997279 = 997430
- 157 + 997273 = 997430
- 163 + 997267 = 997430
Showing the first eight; more decompositions exist.
