Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577714, here are decompositions:

67 + 31577647 = 31577714
127 + 31577587 = 31577714
193 + 31577521 = 31577714
241 + 31577473 = 31577714
313 + 31577401 = 31577714
331 + 31577383 = 31577714
541 + 31577173 = 31577714
601 + 31577113 = 31577714

Showing the first eight; more decompositions exist.
