Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506374, here are decompositions:

7 + 31506367 = 31506374
43 + 31506331 = 31506374
103 + 31506271 = 31506374
127 + 31506247 = 31506374
181 + 31506193 = 31506374
271 + 31506103 = 31506374
283 + 31506091 = 31506374
313 + 31506061 = 31506374

Showing the first eight; more decompositions exist.
