Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601480, here are decompositions:

7 + 31601473 = 31601480
73 + 31601407 = 31601480
139 + 31601341 = 31601480
277 + 31601203 = 31601480
397 + 31601083 = 31601480
439 + 31601041 = 31601480
457 + 31601023 = 31601480
487 + 31600993 = 31601480

Showing the first eight; more decompositions exist.
