Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473346, here are decompositions:

83 + 31473263 = 31473346
137 + 31473209 = 31473346
173 + 31473173 = 31473346
239 + 31473107 = 31473346
263 + 31473083 = 31473346
269 + 31473077 = 31473346
383 + 31472963 = 31473346
419 + 31472927 = 31473346

Showing the first eight; more decompositions exist.
