Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978150, here are decompositions:

37 + 978113 = 978150
59 + 978091 = 978150
71 + 978079 = 978150
73 + 978077 = 978150
79 + 978071 = 978150
83 + 978067 = 978150
97 + 978053 = 978150
101 + 978049 = 978150

Showing the first eight; more decompositions exist.
