Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55742, here are decompositions:
- 31 + 55711 = 55742
- 61 + 55681 = 55742
- 79 + 55663 = 55742
- 103 + 55639 = 55742
- 109 + 55633 = 55742
- 139 + 55603 = 55742
- 163 + 55579 = 55742
- 241 + 55501 = 55742
Showing the first eight; more decompositions exist.
