Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458962, here are decompositions:

61 + 31458901 = 31458962
163 + 31458799 = 31458962
331 + 31458631 = 31458962
373 + 31458589 = 31458962
421 + 31458541 = 31458962
631 + 31458331 = 31458962
1033 + 31457929 = 31458962
1051 + 31457911 = 31458962

Showing the first eight; more decompositions exist.
