Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450004, here are decompositions:

13 + 31449991 = 31450004
37 + 31449967 = 31450004
67 + 31449937 = 31450004
73 + 31449931 = 31450004
151 + 31449853 = 31450004
181 + 31449823 = 31450004
307 + 31449697 = 31450004
331 + 31449673 = 31450004

Showing the first eight; more decompositions exist.
