Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454562, here are decompositions:

79 + 31454483 = 31454562
101 + 31454461 = 31454562
131 + 31454431 = 31454562
173 + 31454389 = 31454562
179 + 31454383 = 31454562
211 + 31454351 = 31454562
241 + 31454321 = 31454562
313 + 31454249 = 31454562

Showing the first eight; more decompositions exist.
