Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498626, here are decompositions:

67 + 31498559 = 31498626
79 + 31498547 = 31498626
97 + 31498529 = 31498626
109 + 31498517 = 31498626
113 + 31498513 = 31498626
127 + 31498499 = 31498626
157 + 31498469 = 31498626
163 + 31498463 = 31498626

Showing the first eight; more decompositions exist.
