Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532048, here are decompositions:

127 + 31531921 = 31532048
139 + 31531909 = 31532048
409 + 31531639 = 31532048
421 + 31531627 = 31532048
577 + 31531471 = 31532048
631 + 31531417 = 31532048
787 + 31531261 = 31532048
991 + 31531057 = 31532048

Showing the first eight; more decompositions exist.
