Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749394, here are decompositions:

37 + 8749357 = 8749394
151 + 8749243 = 8749394
307 + 8749087 = 8749394
421 + 8748973 = 8749394
541 + 8748853 = 8749394
547 + 8748847 = 8749394
607 + 8748787 = 8749394
751 + 8748643 = 8749394

Showing the first eight; more decompositions exist.
