Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606630, here are decompositions:

47 + 31606583 = 31606630
71 + 31606559 = 31606630
89 + 31606541 = 31606630
101 + 31606529 = 31606630
113 + 31606517 = 31606630
131 + 31606499 = 31606630
137 + 31606493 = 31606630
233 + 31606397 = 31606630

Showing the first eight; more decompositions exist.
