Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534700, here are decompositions:

31 + 31534669 = 31534700
103 + 31534597 = 31534700
139 + 31534561 = 31534700
157 + 31534543 = 31534700
199 + 31534501 = 31534700
271 + 31534429 = 31534700
277 + 31534423 = 31534700
331 + 31534369 = 31534700

Showing the first eight; more decompositions exist.
