Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462394, here are decompositions:

13 + 31462381 = 31462394
31 + 31462363 = 31462394
37 + 31462357 = 31462394
43 + 31462351 = 31462394
127 + 31462267 = 31462394
373 + 31462021 = 31462394
433 + 31461961 = 31462394
571 + 31461823 = 31462394

Showing the first eight; more decompositions exist.
