Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598762, here are decompositions:

61 + 31598701 = 31598762
79 + 31598683 = 31598762
241 + 31598521 = 31598762
313 + 31598449 = 31598762
409 + 31598353 = 31598762
463 + 31598299 = 31598762
523 + 31598239 = 31598762
571 + 31598191 = 31598762

Showing the first eight; more decompositions exist.
