Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534846, here are decompositions:

47 + 31534799 = 31534846
59 + 31534787 = 31534846
89 + 31534757 = 31534846
107 + 31534739 = 31534846
137 + 31534709 = 31534846
257 + 31534589 = 31534846
293 + 31534553 = 31534846
353 + 31534493 = 31534846

Showing the first eight; more decompositions exist.

IPv4 address
