Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015240, here are decompositions:

41 + 1015199 = 1015240
101 + 1015139 = 1015240
113 + 1015127 = 1015240
167 + 1015073 = 1015240
173 + 1015067 = 1015240
179 + 1015061 = 1015240
197 + 1015043 = 1015240
251 + 1014989 = 1015240

Showing the first eight; more decompositions exist.
