Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561236, here are decompositions:

7 + 561229 = 561236
37 + 561199 = 561236
127 + 561109 = 561236
139 + 561097 = 561236
157 + 561079 = 561236
307 + 560929 = 561236
349 + 560887 = 561236
367 + 560869 = 561236

Showing the first eight; more decompositions exist.
