Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741990, here are decompositions:

3 + 8741987 = 8741990
7 + 8741983 = 8741990
13 + 8741977 = 8741990
43 + 8741947 = 8741990
67 + 8741923 = 8741990
79 + 8741911 = 8741990
151 + 8741839 = 8741990
193 + 8741797 = 8741990

Showing the first eight; more decompositions exist.
