Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155526, here are decompositions:
- 5 + 155521 = 155526
- 17 + 155509 = 155526
- 53 + 155473 = 155526
- 73 + 155453 = 155526
- 83 + 155443 = 155526
- 103 + 155423 = 155526
- 113 + 155413 = 155526
- 127 + 155399 = 155526
Showing the first eight; more decompositions exist.
