Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455562, here are decompositions:

29 + 31455533 = 31455562
41 + 31455521 = 31455562
59 + 31455503 = 31455562
113 + 31455449 = 31455562
191 + 31455371 = 31455562
263 + 31455299 = 31455562
269 + 31455293 = 31455562
293 + 31455269 = 31455562

Showing the first eight; more decompositions exist.
