Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516004, here are decompositions:

67 + 31515937 = 31516004
73 + 31515931 = 31516004
241 + 31515763 = 31516004
271 + 31515733 = 31516004
307 + 31515697 = 31516004
397 + 31515607 = 31516004
733 + 31515271 = 31516004
787 + 31515217 = 31516004

Showing the first eight; more decompositions exist.
