Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015208, here are decompositions:

37 + 1015171 = 1015208
127 + 1015081 = 1015208
151 + 1015057 = 1015208
157 + 1015051 = 1015208
199 + 1015009 = 1015208
331 + 1014877 = 1015208
421 + 1014787 = 1015208
487 + 1014721 = 1015208

Showing the first eight; more decompositions exist.
