Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87618, here are decompositions:
- 5 + 87613 = 87618
- 29 + 87589 = 87618
- 31 + 87587 = 87618
- 59 + 87559 = 87618
- 61 + 87557 = 87618
- 71 + 87547 = 87618
- 79 + 87539 = 87618
- 101 + 87517 = 87618
Showing the first eight; more decompositions exist.
