Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458104, here are decompositions:

43 + 31458061 = 31458104
193 + 31457911 = 31458104
283 + 31457821 = 31458104
367 + 31457737 = 31458104
397 + 31457707 = 31458104
463 + 31457641 = 31458104
547 + 31457557 = 31458104
757 + 31457347 = 31458104

Showing the first eight; more decompositions exist.
