Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462904, here are decompositions:

3 + 31462901 = 31462904
7 + 31462897 = 31462904
73 + 31462831 = 31462904
97 + 31462807 = 31462904
157 + 31462747 = 31462904
181 + 31462723 = 31462904
313 + 31462591 = 31462904
331 + 31462573 = 31462904

Showing the first eight; more decompositions exist.
