Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79540, here are decompositions:
- 3 + 79537 = 79540
- 47 + 79493 = 79540
- 59 + 79481 = 79540
- 89 + 79451 = 79540
- 107 + 79433 = 79540
- 113 + 79427 = 79540
- 173 + 79367 = 79540
- 191 + 79349 = 79540
Showing the first eight; more decompositions exist.
