Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577692, here are decompositions:

23 + 31577669 = 31577692
59 + 31577633 = 31577692
101 + 31577591 = 31577692
401 + 31577291 = 31577692
431 + 31577261 = 31577692
563 + 31577129 = 31577692
683 + 31577009 = 31577692
701 + 31576991 = 31577692

Showing the first eight; more decompositions exist.
