Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601098, here are decompositions:

47 + 31601051 = 31601098
239 + 31600859 = 31601098
281 + 31600817 = 31601098
479 + 31600619 = 31601098
569 + 31600529 = 31601098
587 + 31600511 = 31601098
647 + 31600451 = 31601098
677 + 31600421 = 31601098

Showing the first eight; more decompositions exist.
