Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468346, here are decompositions:

103 + 31468243 = 31468346
199 + 31468147 = 31468346
379 + 31467967 = 31468346
397 + 31467949 = 31468346
409 + 31467937 = 31468346
499 + 31467847 = 31468346
619 + 31467727 = 31468346
757 + 31467589 = 31468346

Showing the first eight; more decompositions exist.
