Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 602, here are decompositions:
- 3 + 599 = 602
- 31 + 571 = 602
- 61 + 541 = 602
- 79 + 523 = 602
- 103 + 499 = 602
- 139 + 463 = 602
- 163 + 439 = 602
- 181 + 421 = 602
Showing the first eight; more decompositions exist.
