Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601282, here are decompositions:

19 + 31601263 = 31601282
79 + 31601203 = 31601282
103 + 31601179 = 31601282
199 + 31601083 = 31601282
241 + 31601041 = 31601282
313 + 31600969 = 31601282
421 + 31600861 = 31601282
439 + 31600843 = 31601282

Showing the first eight; more decompositions exist.
