Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600670, here are decompositions:

7 + 31600663 = 31600670
139 + 31600531 = 31600670
223 + 31600447 = 31600670
229 + 31600441 = 31600670
313 + 31600357 = 31600670
337 + 31600333 = 31600670
379 + 31600291 = 31600670
397 + 31600273 = 31600670

Showing the first eight; more decompositions exist.
