Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498006, here are decompositions:

3 + 31498003 = 31498006
179 + 31497827 = 31498006
233 + 31497773 = 31498006
269 + 31497737 = 31498006
479 + 31497527 = 31498006
557 + 31497449 = 31498006
563 + 31497443 = 31498006
647 + 31497359 = 31498006

Showing the first eight; more decompositions exist.
