Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526846, here are decompositions:

37 + 31526809 = 31526846
73 + 31526773 = 31526846
97 + 31526749 = 31526846
157 + 31526689 = 31526846
199 + 31526647 = 31526846
229 + 31526617 = 31526846
283 + 31526563 = 31526846
313 + 31526533 = 31526846

Showing the first eight; more decompositions exist.
