Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738782, here are decompositions:

23 + 8738759 = 8738782
53 + 8738729 = 8738782
71 + 8738711 = 8738782
191 + 8738591 = 8738782
383 + 8738399 = 8738782
419 + 8738363 = 8738782
431 + 8738351 = 8738782
443 + 8738339 = 8738782

Showing the first eight; more decompositions exist.
