Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79488, here are decompositions:
- 7 + 79481 = 79488
- 37 + 79451 = 79488
- 61 + 79427 = 79488
- 89 + 79399 = 79488
- 109 + 79379 = 79488
- 131 + 79357 = 79488
- 139 + 79349 = 79488
- 151 + 79337 = 79488
Showing the first eight; more decompositions exist.
