Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551432, here are decompositions:

151 + 551281 = 551432
163 + 551269 = 551432
199 + 551233 = 551432
373 + 551059 = 551432
439 + 550993 = 551432
463 + 550969 = 551432
523 + 550909 = 551432
571 + 550861 = 551432

Showing the first eight; more decompositions exist.
