Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601244, here are decompositions:

41 + 31601203 = 31601244
53 + 31601191 = 31601244
107 + 31601137 = 31601244
167 + 31601077 = 31601244
193 + 31601051 = 31601244
251 + 31600993 = 31601244
383 + 31600861 = 31601244
401 + 31600843 = 31601244

Showing the first eight; more decompositions exist.
