Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454532, here are decompositions:

19 + 31454513 = 31454532
71 + 31454461 = 31454532
101 + 31454431 = 31454532
149 + 31454383 = 31454532
181 + 31454351 = 31454532
211 + 31454321 = 31454532
269 + 31454263 = 31454532
283 + 31454249 = 31454532

Showing the first eight; more decompositions exist.
