Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55442, here are decompositions:
- 3 + 55439 = 55442
- 31 + 55411 = 55442
- 43 + 55399 = 55442
- 61 + 55381 = 55442
- 103 + 55339 = 55442
- 109 + 55333 = 55442
- 151 + 55291 = 55442
- 193 + 55249 = 55442
Showing the first eight; more decompositions exist.
