Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55520, here are decompositions:
- 19 + 55501 = 55520
- 79 + 55441 = 55520
- 109 + 55411 = 55520
- 139 + 55381 = 55520
- 181 + 55339 = 55520
- 229 + 55291 = 55520
- 271 + 55249 = 55520
- 277 + 55243 = 55520
Showing the first eight; more decompositions exist.
