Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590732, here are decompositions:

73 + 31590659 = 31590732
83 + 31590649 = 31590732
101 + 31590631 = 31590732
139 + 31590593 = 31590732
149 + 31590583 = 31590732
181 + 31590551 = 31590732
233 + 31590499 = 31590732
263 + 31590469 = 31590732

Showing the first eight; more decompositions exist.
