Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540594, here are decompositions:

101 + 31540493 = 31540594
251 + 31540343 = 31540594
353 + 31540241 = 31540594
383 + 31540211 = 31540594
431 + 31540163 = 31540594
563 + 31540031 = 31540594
587 + 31540007 = 31540594
773 + 31539821 = 31540594

Showing the first eight; more decompositions exist.
