Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473086, here are decompositions:

3 + 31473083 = 31473086
19 + 31473067 = 31473086
103 + 31472983 = 31473086
157 + 31472929 = 31473086
199 + 31472887 = 31473086
313 + 31472773 = 31473086
499 + 31472587 = 31473086
607 + 31472479 = 31473086

Showing the first eight; more decompositions exist.
