Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550402, here are decompositions:

23 + 550379 = 550402
113 + 550289 = 550402
191 + 550211 = 550402
233 + 550169 = 550402
239 + 550163 = 550402
263 + 550139 = 550402
353 + 550049 = 550402
491 + 549911 = 550402

Showing the first eight; more decompositions exist.
