Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731432, here are decompositions:

5 + 8731427 = 8731432
89 + 8731343 = 8731432
131 + 8731301 = 8731432
293 + 8731139 = 8731432
401 + 8731031 = 8731432
449 + 8730983 = 8731432
503 + 8730929 = 8731432
569 + 8730863 = 8731432

Showing the first eight; more decompositions exist.
