Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55290, here are decompositions:
- 31 + 55259 = 55290
- 41 + 55249 = 55290
- 47 + 55243 = 55290
- 61 + 55229 = 55290
- 71 + 55219 = 55290
- 73 + 55217 = 55290
- 83 + 55207 = 55290
- 89 + 55201 = 55290
Showing the first eight; more decompositions exist.
