Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469048, here are decompositions:

7 + 31469041 = 31469048
199 + 31468849 = 31469048
271 + 31468777 = 31469048
349 + 31468699 = 31469048
577 + 31468471 = 31469048
601 + 31468447 = 31469048
1021 + 31468027 = 31469048
1201 + 31467847 = 31469048

Showing the first eight; more decompositions exist.
