Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700492, here are decompositions:

19 + 8700473 = 8700492
43 + 8700449 = 8700492
61 + 8700431 = 8700492
71 + 8700421 = 8700492
109 + 8700383 = 8700492
131 + 8700361 = 8700492
139 + 8700353 = 8700492
193 + 8700299 = 8700492

Showing the first eight; more decompositions exist.
