Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700442, here are decompositions:

11 + 8700431 = 8700442
41 + 8700401 = 8700442
59 + 8700383 = 8700442
89 + 8700353 = 8700442
281 + 8700161 = 8700442
383 + 8700059 = 8700442
431 + 8700011 = 8700442
449 + 8699993 = 8700442

Showing the first eight; more decompositions exist.
