Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015144, here are decompositions:

5 + 1015139 = 1015144
17 + 1015127 = 1015144
47 + 1015097 = 1015144
71 + 1015073 = 1015144
83 + 1015061 = 1015144
101 + 1015043 = 1015144
191 + 1014953 = 1015144
257 + 1014887 = 1015144

Showing the first eight; more decompositions exist.
