Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591714, here are decompositions:

3 + 31591711 = 31591714
47 + 31591667 = 31591714
113 + 31591601 = 31591714
137 + 31591577 = 31591714
197 + 31591517 = 31591714
293 + 31591421 = 31591714
347 + 31591367 = 31591714
383 + 31591331 = 31591714

Showing the first eight; more decompositions exist.
