Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978202, here are decompositions:

23 + 978179 = 978202
53 + 978149 = 978202
89 + 978113 = 978202
131 + 978071 = 978202
149 + 978053 = 978202
191 + 978011 = 978202
353 + 977849 = 978202
383 + 977819 = 978202

Showing the first eight; more decompositions exist.
