Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87584, here are decompositions:
- 31 + 87553 = 87584
- 37 + 87547 = 87584
- 43 + 87541 = 87584
- 61 + 87523 = 87584
- 67 + 87517 = 87584
- 73 + 87511 = 87584
- 103 + 87481 = 87584
- 151 + 87433 = 87584
Showing the first eight; more decompositions exist.
