Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506344, here are decompositions:

13 + 31506331 = 31506344
61 + 31506283 = 31506344
73 + 31506271 = 31506344
97 + 31506247 = 31506344
151 + 31506193 = 31506344
241 + 31506103 = 31506344
283 + 31506061 = 31506344
313 + 31506031 = 31506344

Showing the first eight; more decompositions exist.
