Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155562, here are decompositions:
- 5 + 155557 = 155562
- 23 + 155539 = 155562
- 41 + 155521 = 155562
- 53 + 155509 = 155562
- 61 + 155501 = 155562
- 89 + 155473 = 155562
- 101 + 155461 = 155562
- 109 + 155453 = 155562
Showing the first eight; more decompositions exist.
