Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473692, here are decompositions:

109 + 31473583 = 31473692
163 + 31473529 = 31473692
379 + 31473313 = 31473692
409 + 31473283 = 31473692
541 + 31473151 = 31473692
631 + 31473061 = 31473692
661 + 31473031 = 31473692
709 + 31472983 = 31473692

Showing the first eight; more decompositions exist.
