Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731098, here are decompositions:

29 + 8731069 = 8731098
59 + 8731039 = 8731098
67 + 8731031 = 8731098
71 + 8731027 = 8731098
149 + 8730949 = 8731098
151 + 8730947 = 8731098
179 + 8730919 = 8731098
197 + 8730901 = 8731098

Showing the first eight; more decompositions exist.
