Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009802, here are decompositions:

61 + 1009741 = 1009802
151 + 1009651 = 1009802
181 + 1009621 = 1009802
193 + 1009609 = 1009802
229 + 1009573 = 1009802
271 + 1009531 = 1009802
433 + 1009369 = 1009802
499 + 1009303 = 1009802

Showing the first eight; more decompositions exist.
