Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506176, here are decompositions:

3 + 31506173 = 31506176
73 + 31506103 = 31506176
193 + 31505983 = 31506176
367 + 31505809 = 31506176
409 + 31505767 = 31506176
439 + 31505737 = 31506176
577 + 31505599 = 31506176
607 + 31505569 = 31506176

Showing the first eight; more decompositions exist.
