Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009172, here are decompositions:

13 + 1009159 = 1009172
19 + 1009153 = 1009172
181 + 1008991 = 1009172
193 + 1008979 = 1009172
271 + 1008901 = 1009172
313 + 1008859 = 1009172
379 + 1008793 = 1009172
601 + 1008571 = 1009172

Showing the first eight; more decompositions exist.
