Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462408, here are decompositions:

59 + 31462349 = 31462408
191 + 31462217 = 31462408
281 + 31462127 = 31462408
401 + 31462007 = 31462408
431 + 31461977 = 31462408
521 + 31461887 = 31462408
557 + 31461851 = 31462408
617 + 31461791 = 31462408

Showing the first eight; more decompositions exist.
