Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87626, here are decompositions:
- 3 + 87623 = 87626
- 13 + 87613 = 87626
- 37 + 87589 = 87626
- 43 + 87583 = 87626
- 67 + 87559 = 87626
- 73 + 87553 = 87626
- 79 + 87547 = 87626
- 103 + 87523 = 87626
Showing the first eight; more decompositions exist.
