Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690472, here are decompositions:

19 + 8690453 = 8690472
59 + 8690413 = 8690472
61 + 8690411 = 8690472
73 + 8690399 = 8690472
101 + 8690371 = 8690472
113 + 8690359 = 8690472
139 + 8690333 = 8690472
179 + 8690293 = 8690472

Showing the first eight; more decompositions exist.
