Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468124, here are decompositions:

97 + 31468027 = 31468124
157 + 31467967 = 31468124
271 + 31467853 = 31468124
277 + 31467847 = 31468124
313 + 31467811 = 31468124
397 + 31467727 = 31468124
433 + 31467691 = 31468124
643 + 31467481 = 31468124

Showing the first eight; more decompositions exist.
