Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601432, here are decompositions:

73 + 31601359 = 31601432
229 + 31601203 = 31601432
241 + 31601191 = 31601432
349 + 31601083 = 31601432
409 + 31601023 = 31601432
439 + 31600993 = 31601432
463 + 31600969 = 31601432
571 + 31600861 = 31601432

Showing the first eight; more decompositions exist.
