Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450532, here are decompositions:

103 + 31450429 = 31450532
109 + 31450423 = 31450532
163 + 31450369 = 31450532
181 + 31450351 = 31450532
241 + 31450291 = 31450532
313 + 31450219 = 31450532
433 + 31450099 = 31450532
439 + 31450093 = 31450532

Showing the first eight; more decompositions exist.
