Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590744, here are decompositions:

5 + 31590739 = 31590744
7 + 31590737 = 31590744
11 + 31590733 = 31590744
13 + 31590731 = 31590744
61 + 31590683 = 31590744
113 + 31590631 = 31590744
127 + 31590617 = 31590744
151 + 31590593 = 31590744

Showing the first eight; more decompositions exist.
