Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003880, here are decompositions:

61 + 1003819 = 1003880
109 + 1003771 = 1003880
127 + 1003753 = 1003880
139 + 1003741 = 1003880
151 + 1003729 = 1003880
271 + 1003609 = 1003880
331 + 1003549 = 1003880
337 + 1003543 = 1003880

Showing the first eight; more decompositions exist.
