Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483756, here are decompositions:

23 + 31483733 = 31483756
107 + 31483649 = 31483756
173 + 31483583 = 31483756
179 + 31483577 = 31483756
263 + 31483493 = 31483756
443 + 31483313 = 31483756
449 + 31483307 = 31483756
587 + 31483169 = 31483756

Showing the first eight; more decompositions exist.
