Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579592, here are decompositions:

73 + 31579519 = 31579592
139 + 31579453 = 31579592
181 + 31579411 = 31579592
193 + 31579399 = 31579592
199 + 31579393 = 31579592
241 + 31579351 = 31579592
271 + 31579321 = 31579592
379 + 31579213 = 31579592

Showing the first eight; more decompositions exist.
