Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87698, here are decompositions:
- 7 + 87691 = 87698
- 19 + 87679 = 87698
- 67 + 87631 = 87698
- 109 + 87589 = 87698
- 139 + 87559 = 87698
- 151 + 87547 = 87698
- 157 + 87541 = 87698
- 181 + 87517 = 87698
Showing the first eight; more decompositions exist.
