Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532642, here are decompositions:

3 + 31532639 = 31532642
61 + 31532581 = 31532642
103 + 31532539 = 31532642
241 + 31532401 = 31532642
313 + 31532329 = 31532642
373 + 31532269 = 31532642
433 + 31532209 = 31532642
439 + 31532203 = 31532642

Showing the first eight; more decompositions exist.
