Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504670, here are decompositions:

3 + 31504667 = 31504670
19 + 31504651 = 31504670
79 + 31504591 = 31504670
97 + 31504573 = 31504670
103 + 31504567 = 31504670
283 + 31504387 = 31504670
313 + 31504357 = 31504670
367 + 31504303 = 31504670

Showing the first eight; more decompositions exist.
