Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455058, here are decompositions:

17 + 31455041 = 31455058
59 + 31454999 = 31455058
101 + 31454957 = 31455058
149 + 31454909 = 31455058
191 + 31454867 = 31455058
317 + 31454741 = 31455058
389 + 31454669 = 31455058
431 + 31454627 = 31455058

Showing the first eight; more decompositions exist.
