Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55390, here are decompositions:
- 17 + 55373 = 55390
- 47 + 55343 = 55390
- 53 + 55337 = 55390
- 59 + 55331 = 55390
- 131 + 55259 = 55390
- 173 + 55217 = 55390
- 227 + 55163 = 55390
- 263 + 55127 = 55390
Showing the first eight; more decompositions exist.
