Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489174, here are decompositions:

31 + 2147489143 = 2147489174
97 + 2147489077 = 2147489174
151 + 2147489023 = 2147489174
157 + 2147489017 = 2147489174
307 + 2147488867 = 2147489174
433 + 2147488741 = 2147489174
601 + 2147488573 = 2147489174
631 + 2147488543 = 2147489174

Showing the first eight; more decompositions exist.
