Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 612, here are decompositions:
- 5 + 607 = 612
- 11 + 601 = 612
- 13 + 599 = 612
- 19 + 593 = 612
- 41 + 571 = 612
- 43 + 569 = 612
- 71 + 541 = 612
- 89 + 523 = 612
Showing the first eight; more decompositions exist.
