Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486706, here are decompositions:

67 + 31486639 = 31486706
73 + 31486633 = 31486706
79 + 31486627 = 31486706
103 + 31486603 = 31486706
157 + 31486549 = 31486706
283 + 31486423 = 31486706
313 + 31486393 = 31486706
367 + 31486339 = 31486706

Showing the first eight; more decompositions exist.
