Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586498, here are decompositions:

37 + 31586461 = 31586498
211 + 31586287 = 31586498
241 + 31586257 = 31586498
367 + 31586131 = 31586498
397 + 31586101 = 31586498
421 + 31586077 = 31586498
439 + 31586059 = 31586498
661 + 31585837 = 31586498

Showing the first eight; more decompositions exist.
