Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614542, here are decompositions:

19 + 31614523 = 31614542
199 + 31614343 = 31614542
313 + 31614229 = 31614542
331 + 31614211 = 31614542
409 + 31614133 = 31614542
433 + 31614109 = 31614542
523 + 31614019 = 31614542
541 + 31614001 = 31614542

Showing the first eight; more decompositions exist.
