Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480006, here are decompositions:

59 + 31479947 = 31480006
149 + 31479857 = 31480006
263 + 31479743 = 31480006
269 + 31479737 = 31480006
359 + 31479647 = 31480006
449 + 31479557 = 31480006
587 + 31479419 = 31480006
809 + 31479197 = 31480006

Showing the first eight; more decompositions exist.
