Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455034, here are decompositions:

3 + 31455031 = 31455034
131 + 31454903 = 31455034
167 + 31454867 = 31455034
197 + 31454837 = 31455034
251 + 31454783 = 31455034
293 + 31454741 = 31455034
353 + 31454681 = 31455034
383 + 31454651 = 31455034

Showing the first eight; more decompositions exist.
