Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87590, here are decompositions:
- 3 + 87587 = 87590
- 7 + 87583 = 87590
- 31 + 87559 = 87590
- 37 + 87553 = 87590
- 43 + 87547 = 87590
- 67 + 87523 = 87590
- 73 + 87517 = 87590
- 79 + 87511 = 87590
Showing the first eight; more decompositions exist.
