Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009148, here are decompositions:

157 + 1008991 = 1009148
211 + 1008937 = 1009148
277 + 1008871 = 1009148
331 + 1008817 = 1009148
367 + 1008781 = 1009148
541 + 1008607 = 1009148
577 + 1008571 = 1009148
601 + 1008547 = 1009148

Showing the first eight; more decompositions exist.
