Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579614, here are decompositions:

47 + 31579567 = 31579614
71 + 31579543 = 31579614
103 + 31579511 = 31579614
137 + 31579477 = 31579614
167 + 31579447 = 31579614
257 + 31579357 = 31579614
263 + 31579351 = 31579614
271 + 31579343 = 31579614

Showing the first eight; more decompositions exist.
