Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606632, here are decompositions:

53 + 31606579 = 31606632
73 + 31606559 = 31606632
89 + 31606543 = 31606632
103 + 31606529 = 31606632
139 + 31606493 = 31606632
163 + 31606469 = 31606632
251 + 31606381 = 31606632
263 + 31606369 = 31606632

Showing the first eight; more decompositions exist.
