Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551972, here are decompositions:

13 + 551959 = 551972
61 + 551911 = 551972
163 + 551809 = 551972
199 + 551773 = 551972
229 + 551743 = 551972
241 + 551731 = 551972
283 + 551689 = 551972
313 + 551659 = 551972

Showing the first eight; more decompositions exist.
