Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460918, here are decompositions:

67 + 31460851 = 31460918
79 + 31460839 = 31460918
109 + 31460809 = 31460918
127 + 31460791 = 31460918
241 + 31460677 = 31460918
271 + 31460647 = 31460918
337 + 31460581 = 31460918
367 + 31460551 = 31460918

Showing the first eight; more decompositions exist.
