Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506824, here are decompositions:

3 + 31506821 = 31506824
31 + 31506793 = 31506824
43 + 31506781 = 31506824
127 + 31506697 = 31506824
313 + 31506511 = 31506824
457 + 31506367 = 31506824
541 + 31506283 = 31506824
577 + 31506247 = 31506824

Showing the first eight; more decompositions exist.
