Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592254, here are decompositions:

41 + 31592213 = 31592254
131 + 31592123 = 31592254
257 + 31591997 = 31592254
461 + 31591793 = 31592254
503 + 31591751 = 31592254
521 + 31591733 = 31592254
587 + 31591667 = 31592254
653 + 31591601 = 31592254

Showing the first eight; more decompositions exist.
