Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574002, here are decompositions:

3 + 31573999 = 31574002
41 + 31573961 = 31574002
71 + 31573931 = 31574002
149 + 31573853 = 31574002
179 + 31573823 = 31574002
359 + 31573643 = 31574002
419 + 31573583 = 31574002
431 + 31573571 = 31574002

Showing the first eight; more decompositions exist.
