Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746378, here are decompositions:

107 + 8746271 = 8746378
149 + 8746229 = 8746378
449 + 8745929 = 8746378
461 + 8745917 = 8746378
521 + 8745857 = 8746378
701 + 8745677 = 8746378
821 + 8745557 = 8746378
827 + 8745551 = 8746378

Showing the first eight; more decompositions exist.
