Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473356, here are decompositions:

43 + 31473313 = 31473356
73 + 31473283 = 31473356
139 + 31473217 = 31473356
193 + 31473163 = 31473356
373 + 31472983 = 31473356
769 + 31472587 = 31473356
877 + 31472479 = 31473356
907 + 31472449 = 31473356

Showing the first eight; more decompositions exist.
