Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447466, here are decompositions:

73 + 31447393 = 31447466
103 + 31447363 = 31447466
109 + 31447357 = 31447466
199 + 31447267 = 31447466
277 + 31447189 = 31447466
367 + 31447099 = 31447466
397 + 31447069 = 31447466
439 + 31447027 = 31447466

Showing the first eight; more decompositions exist.
