Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600654, here are decompositions:

131 + 31600523 = 31600654
233 + 31600421 = 31600654
347 + 31600307 = 31600654
353 + 31600301 = 31600654
461 + 31600193 = 31600654
521 + 31600133 = 31600654
593 + 31600061 = 31600654
653 + 31600001 = 31600654

Showing the first eight; more decompositions exist.
