Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606804, here are decompositions:

101 + 31606703 = 31606804
107 + 31606697 = 31606804
113 + 31606691 = 31606804
137 + 31606667 = 31606804
263 + 31606541 = 31606804
311 + 31606493 = 31606804
431 + 31606373 = 31606804
461 + 31606343 = 31606804

Showing the first eight; more decompositions exist.
