Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601324, here are decompositions:

61 + 31601263 = 31601324
241 + 31601083 = 31601324
283 + 31601041 = 31601324
331 + 31600993 = 31601324
367 + 31600957 = 31601324
463 + 31600861 = 31601324
523 + 31600801 = 31601324
541 + 31600783 = 31601324

Showing the first eight; more decompositions exist.
