Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527990, here are decompositions:

3 + 527987 = 527990
7 + 527983 = 527990
61 + 527929 = 527990
109 + 527881 = 527990
139 + 527851 = 527990
181 + 527809 = 527990
241 + 527749 = 527990
367 + 527623 = 527990

Showing the first eight; more decompositions exist.
