Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535492, here are decompositions:

73 + 31535419 = 31535492
151 + 31535341 = 31535492
181 + 31535311 = 31535492
229 + 31535263 = 31535492
349 + 31535143 = 31535492
379 + 31535113 = 31535492
409 + 31535083 = 31535492
433 + 31535059 = 31535492

Showing the first eight; more decompositions exist.

IPv4 address
