Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448700, here are decompositions:

7 + 31448693 = 31448700
53 + 31448647 = 31448700
61 + 31448639 = 31448700
79 + 31448621 = 31448700
97 + 31448603 = 31448700
113 + 31448587 = 31448700
149 + 31448551 = 31448700
167 + 31448533 = 31448700

Showing the first eight; more decompositions exist.
