Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87814, here are decompositions:
- 3 + 87811 = 87814
- 11 + 87803 = 87814
- 17 + 87797 = 87814
- 47 + 87767 = 87814
- 71 + 87743 = 87814
- 113 + 87701 = 87814
- 131 + 87683 = 87814
- 173 + 87641 = 87814
Showing the first eight; more decompositions exist.
