Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468490, here are decompositions:

19 + 31468471 = 31468490
37 + 31468453 = 31468490
43 + 31468447 = 31468490
331 + 31468159 = 31468490
463 + 31468027 = 31468490
523 + 31467967 = 31468490
541 + 31467949 = 31468490
643 + 31467847 = 31468490

Showing the first eight; more decompositions exist.
