Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458062, here are decompositions:

73 + 31457989 = 31458062
151 + 31457911 = 31458062
193 + 31457869 = 31458062
241 + 31457821 = 31458062
421 + 31457641 = 31458062
613 + 31457449 = 31458062
733 + 31457329 = 31458062
751 + 31457311 = 31458062

Showing the first eight; more decompositions exist.
