Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748490, here are decompositions:

17 + 8748473 = 8748490
59 + 8748431 = 8748490
71 + 8748419 = 8748490
131 + 8748359 = 8748490
167 + 8748323 = 8748490
227 + 8748263 = 8748490
281 + 8748209 = 8748490
347 + 8748143 = 8748490

Showing the first eight; more decompositions exist.
