Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468184, here are decompositions:

37 + 31468147 = 31468184
157 + 31468027 = 31468184
331 + 31467853 = 31468184
337 + 31467847 = 31468184
373 + 31467811 = 31468184
421 + 31467763 = 31468184
457 + 31467727 = 31468184
463 + 31467721 = 31468184

Showing the first eight; more decompositions exist.
