Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463038, here are decompositions:

59 + 31462979 = 31463038
107 + 31462931 = 31463038
137 + 31462901 = 31463038
149 + 31462889 = 31463038
227 + 31462811 = 31463038
281 + 31462757 = 31463038
389 + 31462649 = 31463038
449 + 31462589 = 31463038

Showing the first eight; more decompositions exist.
