Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468700, here are decompositions:

103 + 31468597 = 31468700
127 + 31468573 = 31468700
157 + 31468543 = 31468700
229 + 31468471 = 31468700
331 + 31468369 = 31468700
457 + 31468243 = 31468700
499 + 31468201 = 31468700
541 + 31468159 = 31468700

Showing the first eight; more decompositions exist.
