Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55572, here are decompositions:
- 31 + 55541 = 55572
- 43 + 55529 = 55572
- 61 + 55511 = 55572
- 71 + 55501 = 55572
- 103 + 55469 = 55572
- 131 + 55441 = 55572
- 173 + 55399 = 55572
- 191 + 55381 = 55572
Showing the first eight; more decompositions exist.
