Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447602, here are decompositions:

19 + 31447583 = 31447602
29 + 31447573 = 31447602
73 + 31447529 = 31447602
163 + 31447439 = 31447602
223 + 31447379 = 31447602
239 + 31447363 = 31447602
269 + 31447333 = 31447602
349 + 31447253 = 31447602

Showing the first eight; more decompositions exist.
