Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469174, here are decompositions:

31 + 31469143 = 31469174
43 + 31469131 = 31469174
73 + 31469101 = 31469174
181 + 31468993 = 31469174
211 + 31468963 = 31469174
271 + 31468903 = 31469174
313 + 31468861 = 31469174
397 + 31468777 = 31469174

Showing the first eight; more decompositions exist.
