Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455062, here are decompositions:

31 + 31455031 = 31455062
109 + 31454953 = 31455062
139 + 31454923 = 31455062
181 + 31454881 = 31455062
409 + 31454653 = 31455062
601 + 31454461 = 31455062
631 + 31454431 = 31455062
673 + 31454389 = 31455062

Showing the first eight; more decompositions exist.
