Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469300, here are decompositions:

7 + 31469293 = 31469300
13 + 31469287 = 31469300
61 + 31469239 = 31469300
103 + 31469197 = 31469300
157 + 31469143 = 31469300
199 + 31469101 = 31469300
307 + 31468993 = 31469300
337 + 31468963 = 31469300

Showing the first eight; more decompositions exist.
