Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456030, here are decompositions:

17 + 31456013 = 31456030
71 + 31455959 = 31456030
83 + 31455947 = 31456030
101 + 31455929 = 31456030
227 + 31455803 = 31456030
269 + 31455761 = 31456030
317 + 31455713 = 31456030
383 + 31455647 = 31456030

Showing the first eight; more decompositions exist.
