Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741900, here are decompositions:

61 + 8741839 = 8741900
103 + 8741797 = 8741900
151 + 8741749 = 8741900
157 + 8741743 = 8741900
337 + 8741563 = 8741900
367 + 8741533 = 8741900
379 + 8741521 = 8741900
397 + 8741503 = 8741900

Showing the first eight; more decompositions exist.
