Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468958, here are decompositions:

97 + 31468861 = 31468958
109 + 31468849 = 31468958
181 + 31468777 = 31468958
487 + 31468471 = 31468958
727 + 31468231 = 31468958
757 + 31468201 = 31468958
811 + 31468147 = 31468958
991 + 31467967 = 31468958

Showing the first eight; more decompositions exist.
