Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031888, here are decompositions:

19 + 1031869 = 1031888
79 + 1031809 = 1031888
127 + 1031761 = 1031888
157 + 1031731 = 1031888
181 + 1031707 = 1031888
211 + 1031677 = 1031888
367 + 1031521 = 1031888
409 + 1031479 = 1031888

Showing the first eight; more decompositions exist.
