Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606792, here are decompositions:

89 + 31606703 = 31606792
101 + 31606691 = 31606792
131 + 31606661 = 31606792
149 + 31606643 = 31606792
233 + 31606559 = 31606792
251 + 31606541 = 31606792
263 + 31606529 = 31606792
293 + 31606499 = 31606792

Showing the first eight; more decompositions exist.
