Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547630, here are decompositions:

13 + 31547617 = 31547630
73 + 31547557 = 31547630
151 + 31547479 = 31547630
181 + 31547449 = 31547630
313 + 31547317 = 31547630
349 + 31547281 = 31547630
421 + 31547209 = 31547630
487 + 31547143 = 31547630

Showing the first eight; more decompositions exist.
