Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461432, here are decompositions:

5 + 31461427 = 31461432
19 + 31461413 = 31461432
29 + 31461403 = 31461432
71 + 31461361 = 31461432
83 + 31461349 = 31461432
89 + 31461343 = 31461432
131 + 31461301 = 31461432
139 + 31461293 = 31461432

Showing the first eight; more decompositions exist.
