Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606040, here are decompositions:

127 + 31605913 = 31606040
163 + 31605877 = 31606040
229 + 31605811 = 31606040
283 + 31605757 = 31606040
313 + 31605727 = 31606040
421 + 31605619 = 31606040
457 + 31605583 = 31606040
463 + 31605577 = 31606040

Showing the first eight; more decompositions exist.
