Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576658, here are decompositions:

19 + 31576639 = 31576658
79 + 31576579 = 31576658
109 + 31576549 = 31576658
181 + 31576477 = 31576658
199 + 31576459 = 31576658
241 + 31576417 = 31576658
307 + 31576351 = 31576658
397 + 31576261 = 31576658

Showing the first eight; more decompositions exist.
