Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447562, here are decompositions:

199 + 31447363 = 31447562
229 + 31447333 = 31447562
373 + 31447189 = 31447562
463 + 31447099 = 31447562
541 + 31447021 = 31447562
613 + 31446949 = 31447562
691 + 31446871 = 31447562
709 + 31446853 = 31447562

Showing the first eight; more decompositions exist.
