Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447346, here are decompositions:

13 + 31447333 = 31447346
79 + 31447267 = 31447346
157 + 31447189 = 31447346
277 + 31447069 = 31447346
349 + 31446997 = 31447346
373 + 31446973 = 31447346
397 + 31446949 = 31447346
409 + 31446937 = 31447346

Showing the first eight; more decompositions exist.
