Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455594, here are decompositions:

61 + 31455533 = 31455594
73 + 31455521 = 31455594
167 + 31455427 = 31455594
197 + 31455397 = 31455594
223 + 31455371 = 31455594
227 + 31455367 = 31455594
281 + 31455313 = 31455594
293 + 31455301 = 31455594

Showing the first eight; more decompositions exist.
