Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601144, here are decompositions:

7 + 31601137 = 31601144
61 + 31601083 = 31601144
67 + 31601077 = 31601144
103 + 31601041 = 31601144
151 + 31600993 = 31601144
283 + 31600861 = 31601144
373 + 31600771 = 31601144
613 + 31600531 = 31601144

Showing the first eight; more decompositions exist.
