Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462858, here are decompositions:

47 + 31462811 = 31462858
101 + 31462757 = 31462858
107 + 31462751 = 31462858
269 + 31462589 = 31462858
281 + 31462577 = 31462858
311 + 31462547 = 31462858
419 + 31462439 = 31462858
509 + 31462349 = 31462858

Showing the first eight; more decompositions exist.
