Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482758, here are decompositions:

127 + 31482631 = 31482758
199 + 31482559 = 31482758
331 + 31482427 = 31482758
409 + 31482349 = 31482758
421 + 31482337 = 31482758
487 + 31482271 = 31482758
661 + 31482097 = 31482758
691 + 31482067 = 31482758

Showing the first eight; more decompositions exist.
