Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537706, here are decompositions:

19 + 31537687 = 31537706
97 + 31537609 = 31537706
103 + 31537603 = 31537706
163 + 31537543 = 31537706
199 + 31537507 = 31537706
229 + 31537477 = 31537706
367 + 31537339 = 31537706
379 + 31537327 = 31537706

Showing the first eight; more decompositions exist.
