Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517194, here are decompositions:

131 + 31517063 = 31517194
167 + 31517027 = 31517194
173 + 31517021 = 31517194
353 + 31516841 = 31517194
383 + 31516811 = 31517194
491 + 31516703 = 31517194
563 + 31516631 = 31517194
701 + 31516493 = 31517194

Showing the first eight; more decompositions exist.
