Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978260, here are decompositions:

37 + 978223 = 978260
43 + 978217 = 978260
79 + 978181 = 978260
103 + 978157 = 978260
109 + 978151 = 978260
181 + 978079 = 978260
193 + 978067 = 978260
211 + 978049 = 978260

Showing the first eight; more decompositions exist.
