Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474162, here are decompositions:

89 + 31474073 = 31474162
101 + 31474061 = 31474162
191 + 31473971 = 31474162
353 + 31473809 = 31474162
383 + 31473779 = 31474162
563 + 31473599 = 31474162
569 + 31473593 = 31474162
683 + 31473479 = 31474162

Showing the first eight; more decompositions exist.
