Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468300, here are decompositions:

11 + 31468289 = 31468300
29 + 31468271 = 31468300
41 + 31468259 = 31468300
53 + 31468247 = 31468300
89 + 31468211 = 31468300
131 + 31468169 = 31468300
233 + 31468067 = 31468300
317 + 31467983 = 31468300

Showing the first eight; more decompositions exist.
