Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447592, here are decompositions:

19 + 31447573 = 31447592
151 + 31447441 = 31447592
199 + 31447393 = 31447592
229 + 31447363 = 31447592
523 + 31447069 = 31447592
571 + 31447021 = 31447592
619 + 31446973 = 31447592
643 + 31446949 = 31447592

Showing the first eight; more decompositions exist.
