Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473702, here are decompositions:

103 + 31473599 = 31473702
109 + 31473593 = 31473702
173 + 31473529 = 31473702
179 + 31473523 = 31473702
223 + 31473479 = 31473702
389 + 31473313 = 31473702
419 + 31473283 = 31473702
439 + 31473263 = 31473702

Showing the first eight; more decompositions exist.
